Operational functionality of the device is not implied at these or any other conditions in the excess of those given in the operations sections of the data sheet. Exposure to the absolute maximum ratings for extended periods may adversely affect the device reliability. Electrical Specifications Unless otherwise indicated, specifications apply for all operating input voltages, resistive load and temperature conditions. Technical Specifications Parameter Symbol Min Max Unit Input Voltage (continuous) VIN -0.3 14.5 V Operating Ambient Temperature TA -40+ 85 °C Storage Temperature -55 125 °C CAUTION: This power module is not internally fused. An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to an integrated part of sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included, however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fast -acting fuse with a maximum rating of 40 A, 100 Vdc (see Safety Considerations section). Based on the information provided in this Data Sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer ’s Data Sheet for further information.

Technical Specifications (continued) Safety Considerations For safety agency approval the power module must be installed in compliance with the spacing and separation requirements of the end -use safety agency standards, i.e., UL* 62368 -1, 3rd Ed. Recognized, and VDE (EN62368-1, 3nd Ed.) Licensed. For the converter output to be considered meeting the requirements of safety extra -low voltage (SELV) or ES1, the input must meet SELV/ES1 requirements. The power module has extra low voltage (ELV) outputs when all inputs are ELV. The MLX080A0X model was tested using an external Littelfuse 456 series fast -acting fuse rated at 40A, 100Vdc in the ungrounded input. The maximum hot spot temperature, measured on IC200/C202 shall not exceed 120/115°C Remote On/Off The NexGen module can be turned ON and OFF either by using the ON/OFF pin (Analog interface) or through the PMBus interface (Digital). The module can be configured in a number of ways through the PMBus interface to react to the ON/OFF input:

• Module ON/OFF can controlled only through the analog interface (digital interface ON/OFF commands are ignored)
• Module ON/OFF can controlled only through the PMBus interface (analog interface is ignored)
• Module ON/OFF can be controlled by either the analog or digital interface The default state of the module (as shipped from the factory) is to be controlled by the PMBus interface and analog interface. If the module is to be controlled only through the digital interface, this change must be made through the PMBus. These changes can be made and written to non -volatile memory on the module so that it is remembered for subsequent use. The ON/OFF pin should not be left floating and must be pulled either high or low . Digital On/Off Please see the Digital Feature Descriptions section. Monotonic Start-up and Shutdown The module has monotonic start -up and shutdown behavior on the output for any combination of rated input voltage, output current and operating temperature range. Startup into Pre-biased Output The module will start into a pre biased output on output as long as the pre bias voltage is 15% less than the set output voltage. Remote Sense The power module has a differential Remote Sense feature to minimize the effects of distribution losses by regulating the voltage between the sense pins (VS+ and VS -) for the output. The voltage drop between the sense pins and the VOUT and GND pins of the module should not exceed 100mV.

© 2021 ABB. All rights reserved. Technical Specifications (continued) Non-volatile memory management The MLX080A0XY3 -SRZ has internal non -volatile memory where module’s configurations are stored. During the initialization process, the MLX080A0XY3 - SRZ checks for stored values contained in its internal non-volatile memory. The MLX080 offers up to 24 writes to configure basic module parameters such as output voltage setpoint, fault operation settings, etc. It also allows loading of pre -installed configuration file from upto 15 options to help set multiple MLX modules powering different rails on a common PMBus. Layout considerations The evaluation board layout and schematic files are available for interested users. These can be downloaded through the webpage or by contacting ABB through the web request or helpline. The output overcurrent warning limits and fault response is managed Overtemperature protection The MLX080A0XY3 -SRZ overtemperature protection ensures the temperature inside the module is below component’s temperature maximum limit. The overtemperature protections are managed by the following commands: OT_FAULT_RESPONSE 0x50, OT_WARN_LIMIT 0x51. See commands description for more details. Monitoring through SMBAlert or SALERT pin The MLX080A0XY3 -SRZ controller can monitor for fault conditions by monitoring the SMBALERT pin, which is asserted when any number of preconfigured fault conditions occur. The module can also be monitored continuously for any number of power conversion parameters. Some of most useful monitoring commands are: STATUS_BYTE 0x78, STATUS_WORD 0x79, STATUS_VOUT 0x7A, STATUS_IOUT 0x7B, STATUS_INPUT 0x7C, STATUS_TEMPERATURE 0x7D. For the full list of available commands see the table of supported PMBus commands. Control loop tuning The heart of MLX080A0XY3 -SRZ is a fully digital controller IC with state -of-the-art PID Control. By default, this control loop is stable for minimum recommended output capacitance and loads. However, it may be further tuned to achieve higher performance under more specific application requirements. Since the control scheme is digital from end to end there is no dependence upon external compensation networks. This simplifies the design process by removing such considerations as temperature and process variation of passive components. Control parameters are set through the DO(h) PMBus command—See Application Note IOUT_OC_WARN_LIMIT 0x4A, IOUT_OC_FAULT_RESPONSE 0X47

© 2021 ABB. All rights reserved. Technical Specifications (continued) Digital Compensator The MLX080 module uses digital control to regulate the output voltage. As with all POL modules, external capacitors are usually added to the output of the module for two reasons: to reduce output ripple and noise and to reduce output voltage deviations from the steady-state value in the presence of dynamic load current changes. The MLX080 comes with default compensation values programmed into the non -volatile memory of the module. These digital compensation values can be adjusted externally to optimize transient response and ensure stability for a wide range of external capacitance, as well as with different types of output capacitance. Table 1 Output Capacitors S1 S2 P I D 15x22uF + 24x47uF + 4x470uF 5 7 42 22 58 15x22uF + 65x47uF + 4x470uF 5 7 42 22 58 15x22uF + 73x47uF + 6x470uF 5 7 42 22 58 Power Module Wizard Designers can access a free, web -based, easy to use tool that helps users simulate and tune the MLX080A0XY3 - SRZ feedback loop parameters. Go to http://abb.transim.com and sign up for a free account to use the module selector tool. The tool also offers online Simplis/Simetrix models that can be used to assess transient performance, module stability, etc. Digital Power Insight (DPI) A software tool that helps users evaluate and simulate the PMBus performance of the MLX080A0XY3A modules without the need to write software is also available. The software can be downloaded for free from our webpage. A USB to I 2C adapter and associated cable set are required for proper functioning of the software suite. For first time users, we recommend using the DPI Evaluation Kit, which can be purchased from any of the leading distributors. Please ensure that the USB to I 2C adapter being used/purchased is Version 2.2 or higher. Part Numbers are available in the last few pages of this datasheet

© 2021 ABB. All rights reserved. Technical Specifications (continued) PMBus use guidelines An I2C or PMBus interface is used to communicate with the module. These two -wire serial interfaces consist of clock and data signals, and operate as fast as 1 MHz with proper signal integrity. 400kHz is the typical operating frequency. The bus provides read & write access to the internal registers for configuration, and for monitoring of operating parameters. The bus is also used to program on -chip non -volatile memory (MTP) to store operating parameters. To ensure operation with multiple devices on the bus, an exclusive address for the module is programmed into MTP. To protect customer configuration and information, the I2C interface can be configured for either limited access or locked with a 16 -bit software password. Limited access includes both write and read protection options. In addition, there is a telemetry -only mode which only allows reads from the telemetry registers. The module supports the Packet Error Checking (PEC) protocol and a number of PMBus commands to monitor voltages and currents PMBus data format Linear-11 The L11 data format uses 5 -bit two’s complement exponent (N) and 11 -bit two’s complement mantissa (Y) to represent real world decimal value (X). The relation between real world decimal value (X), N, and Y is: X = Y•2N. Linear-16 The L16u data format uses a fixed exponent (hard -coded to N = -xxh) and a 16 -bit unsigned integer mantissa (Y) to represent real world decimal value (X). The relation between real world decimal value (X), N, and Y is: X = Y•2-xx. Linear-16 Signed The L16s data format uses a fixed exponent (hard -coded to N = -xxh) and a 16 -bit two ’s complement mantissa (Y) to represent real world decimal value (X). The relation between real world decimal value (X), N, and Y is: X = Y•2-xx. Bit Field A description of the Bit Field format is provided in each command details. Custom A description of the Custom data format is provided in each command details. A combination of Bit Field PMBus Addressing The power module is addressed through the PMBus using a device address. The default module address is 40(h). The module supports 15 possible offset addresses (40 to 55) in Hex. If multiple modules are used on the same bus user must power up each module individually, change the module address and then move on to the next module and repeat the process. If this is not possible, a pre -defined resistor can be connected to the PROG pin to provide an offset to the default address yielding a different address for each module on the same bus as described later in this document.

© 2021 ABB. All rights reserved. Technical Specifications (continued) PMBus Addressing The module simultaneously supports I2C and PMBus through the use of exclusive addressing. By using a 7 -bit address, the user can configure the device to any one of 127 different I2C/PMBus addresses. Once the address of is set, it can be locked to protect it from being overridden. Optionally, a resistor can be tied to the PROG pin to generate an offset as shown in Table below (note that a 0.01 μF capacitor is required across the resistor). The base I2C address is 10h and Base PMBus address Is 40h. For default programmed devices, the I2C/PMBus address can be temporarily forced to 0Ah for I2C and 0Dh for PMBus by driving the PROG pin high (3.3 V). The module supports 15 possible offset addresses (40 to 55) in Hex through resistor connection to the PROG pin. If multiple modules are used on the same bus without different PROG pin resistors, user must power up each module individually, change the module address and then move on to the next module and repeat the process. (See Quick Start Process in this datasheet). D0 sub-commands show register used to set and lock PMBus address and offset. Example for 3 MLX modules on the same PMBus channel, select a 0.845K ohm resistor on program pin of module 1 , 1.3kohm resistor on module 2 and a 1.78kohm resistor on module 3. This results in: Module 1 : I2C address is 10h+0h=10h, PMBus address is 40h+0h=40h Module 2 : I2C address is 10h+1h=11h, PMBus address is 40h+1h=41h Module 3 : I2C address is 10h+2h=12h, PMBus address is 40h+2h=42h PROG RESISTOR I2C Address Offset 0.845kΩ +0 1.3kΩ +1 1.78kΩ +2 4.12kΩ +6 3.48kΩ +5 2.32kΩ +3 2.87kΩ +4 4.75kΩ +7 11.00kΩ +14 5.49kΩ +8 6.19kΩ +9 6.98kΩ +10 7.87kΩ +11 8.87kΩ +12 10.00kΩ +13 12.10kΩ +15

© 2021 ABB. All rights reserved. Technical Specifications (continued) Surface Mount Information (continued) MSL Rating The MLX080A0XY3-SRZ Open Frame modules have a MSL rating of 2A. Storage and Handling The recommended storage environment and handling procedures for moisture -sensitive surface mount packages is detailed in J -STD-033 Rev. A (Handling, Packing, Shipping and Use of Moisture/Reflow Sensitive Surface Mount Devices). Moisture barrier bags (MBB) with desiccant are required for MSL ratings of 2 or greater. These sealed packages should not be broken until time of use. Once the original package is broken, the floor life of the product at conditions of 30°C and 60% relative humidity varies according to the MSL rating (see J -STD- 033A). The shelf life for dry packed SMT packages will be a minimum of 12 months from the bag seal date, when stored at the following conditions: < 40° C, < 90% relative humidity. Post Solder Cleaning and Drying Considerations Post solder cleaning is usually the final circuit -board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly. For guidance on appropriate soldering, cleaning and drying procedures, refer to Board Mounted Power Modules: Soldering and Cleaning Application Note (AN04 -001).
