Description

The PT4410 series of power modules are single- output isolated DC/DC converters, housed in a compact 21-pin low-profile (12 mm) package. These modules are rated up to 100W with load currents as high as 30 A. The output voltage is set within a pre-defined range via a 5-bit input code. The PT4410 series operates from a standard 48-V telecom CO supply and occupies only 3.9 in² of PCB area. These modules offer OEMs a compact and flexible high-output power source for use with high-end microprocessors, DSPs, general purpose logic and analog. They are suitable for distributed power applications in both telecom and computing environments. Features include output over-current protection, on/off control, output over-voltage protection (OVP), over-temperature shutdown, under-volt- age lockout (UVLO), and an output differential remote sense. The modules are fully integrated for stand-alone operation, and require no additional components. The horizontal package outline is also comparable to industry standard ¼-bricks, allowing for a dual PWB layout.

When powering the module from a –48-V telecom central office supply, this input is connected to the primary system ground. –Vin: The negative input supply for the module, and the 0 VDC reference for the Remote On/Off input. When powering the module from a +48-V supply, this input is connected to the 48-V(Return). Remote On/Off: An open-collector (open-drain) positive logic input that is referenced to –V in. Pulling this input down to –V in potential disables the module’s output. If this input is left open-circuit, the module will produce an output whenever a valid input source is applied. VID0 – VID4: Selects the set-point output voltage of the converter according to the applicable program code. VID0 – VID4 must either be connected to (–)Remote Sense or left open circuit. Note: For the PT4412, VID 4 is internally disabled and may be left open circuit. +Vo: The positive power output with respect to -Vo, which is DC isolated from the input supply pins. If a negative output voltage is desired, +Vo should be connected to the secondary circuit common and the output taken from –Vo. –Vo: The negative power output with respect to +V o, which is DC isolated from the input supply pins. This output is normally connected to the secondary circuit common when a positive output voltage is desired. +Remote Sense: Provides the converter with remote sense capability to regulate the set-point voltage directly at the load. When used with –Remote Sense, the regulation circuitry will compensate for voltage drop between the converter and the load. The pin may be left open circuit, but connecting it to +V o will improve load regulation. –Remote Sense: This is the logic ‘0’ reference for the inputs VID0 – VID4, and provides the converter with remote sense capability when used in conjunction with +Remote Sense. For optimum output voltage accuracy this pin should always be connected to –V PT4412 VID4= NC Vout N/D * 1.05 V 1.10 V 1.15 V 1.20 V 1.25 V 1.30 V 1.35 V 1.40 V 1.45 V 1.50 V 1.55 V 1.60 V 1.65 V 1.70 V 1.75 V * N/D = Voltage is not defined.

For technical support and more information, see inside back cover or visit www.ti.com PT4400/4410 Series Operating Features and System Considerations for the PT4400/PT4410 Series of DC/DC Converters Over-Current Protection T o protect against load faults these converters incorporate output over-current protection. Applying a load to the output that exceeds the converter’s over-current threshold (see applicable specification) will cause the output voltage to momentarily fold back, and then shut down. Following shutdown the module will periodically attempt to auto- matically r ecover by initiating a soft-start power-up. This is often described as a “hiccup” mode of operation, whereby the module continues in the cycle of successive shutdown and power up until the load fault is removed. Once the fault is removed, the converter automatically recovers and returns to normal operation. Output Over-Voltage Protection Each converter incorporates protection circuitry that continually senses for an output overvoltage (OV) condi- tion. The O V threshold auto matically tracks the VID output voltage program setting to a level that is 25 % higher than that programmed at the control pins, VID0 through VID4. If the converter output voltage exceeds this threshold, the converter is immediately shut down and remains in a latched-off state. To resume normal operation the converter must be actively reset. This can only be done by momentarily removing the input power to the converter. For failsafe operation and redundancy, the O V protection uses circuitry that is independent of the converter’s internal feedback loop. Over-Temperature Protection Over-temperature protection is provided by an internal temperature sensor, which closely monitors the tempera- ture of the converter’s metal case. If the case temperature exceeds a nominal 115 °C, the converter will shut down. The converter will then automatically restart when the sensed temperature drops back to approximately 105 °C. When operated outside its recommended thermal derating envelope (see data sheet SOA curves), the converter will typcially cycle on and off at intervals from a few seconds to one or two minutes. This is to ensure that the internal components are not permanently damaged from exces- sive thermal stress. Under-Voltage Lockout The Under-Voltage Lock-Out (UVLO) is designed to prevent the operation of the converter until the input voltage is close to the minimum input voltage. The converter is held off when the input voltage is below the UVLO threshold, and turns on when the input voltage rises above the threshold. This prevents high start-up current during normal power-up of the converter, and minimizes the current drain from the input source during low input voltage conditions. The converter will meet full specifications when the minimum specified input voltage is reached. The UVLO circuitry also overrides the operation of the Remote On/Off control. Only when the input voltage is above the UVLO threshold will the Remote On/Off control be functional. Primary-Secondary Isolation These converters incorporate electrical isolation between the input terminals (primary) and the output terminals (secondary). All converters are production tested to a withstand voltage of 1500VDC. This specification com- plies with UL60950 and EN60950 and the requirements for operational isolation. This allows the converter to be configured for either a positive or negative input voltage source. The data sheet ‘Pin Descriptions’ section provides guidance as to the correct reference that must be used for the external control signals. Input Current Limiting The converter is not internally fused. For safety and overall system protection, the maximum input current to the converter must be limited. Active or passive current limiting can be used. Passive current limiting can be a fast acting fuse. A 125-V fuse, rated no more than 10 A, is recommended. Active current limiting can be imple- mented with a current limited “Hot-Swap” controller. Thermal Considerations Airflow may be necessary to ensure that the module can supply the desired load current in environments with elevated ambient temperatures. The required airflow rate may be determined from the Safe Operating Area (SOA) thermal derating chart (see converter specifica- tions). The recommended direction for airflow is into, or perpendicular to, the longest side of the module’s metal case. See Figure 1. Recommended direction for airflow is into (perpendicular to) the longest side. Figure 1

For technical support and more information, see inside back cover or visit www.ti.com PT4400/4410 Series Pin-Coded Output Voltage Adjustment on the PT4400/4410 Series of DC/DC Converters These DC/DC converters have a programmable output voltage. In each case the desired output voltage must be selected from one of a number of discrete voltages using the voltage programming control pins. Depending on each model’s resolution and adjustment range, there are up to five control pins. They are identified VID0–VID4 (pins 7–11) respectively. By selectively strapping these control pins to (–)Remote Sense (pin 12), the output voltage can be programmed to one of up to 32 different values over the defined output voltage range. The program code and output voltage range of the PT4401/4411 is also compatible with the “Voltage ID” code defined in the Intel® VRM 8.2 specification. Refer to the applicable product specification sheet for the program code. Notes: 1.The programming convention is as follows:- Logic 0: Connect to pin 12 (–Remote Sense). Logic 1: Open circuit/open drain (See notes 2, & 4) 2.Do not connect pull-up resistors to the voltage programming pins. 3.T o minimize output voltage error, always use pin 12 (-Remote Sense) as the logic “0” reference. While -Vout (pins 13-16) can also be used for programming, doing so will degrade the voltage selection accuracy and load regulation of the product. 4.When VID0–VID4 are all open circuit (logic 1), the output voltage is undefined. In this state the output voltage of the converter cannot be guaranteed, and can vary with output load and input voltage. 5.On all models other than the PT4401/4411, the contol Figure 1 input VID4 (pin 11) is internally disabled and is not functional. 6.If active devices are used to ground the voltage control pins, low-level open drain MOSFET devices should be used over bipolar transistors. The inherent Vce(sat) in bipolar devices introduces errors in the device’ s internal voltage control circuit. Discrete transistors such as the BSS138 or IRLML2402 are examples of appropriate devices. Active Voltage Programming: Special precautions should be taken when making changes to the voltage progam code while the output is active. This activity induces a transient, which may activate the module’s output over-voltage (OV) protection. Once triggered the OV protection circuit latches the output off, and requires the momentary removal of input power to reset the module. OV protection trips can be avoided by limiting the output voltage adjustment to no more than a 15 % change from the initial voltage. Large transi- tions are best made with a series of incremental changes, allowing 100 µs settling time between each program state. When using active devices to program the output voltage, their state should be asserted prior to input power being applied. An alternative is to pull pin 1 ( Remote On/Off) to in (pins 2, 3) during the application of power, assert the required program code, and then release pin 1. The mod- ule will than initiate a soft-start power-up to the desired program voltage.

The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
