TYPICAL PERFORMANCE CHARACTERISTICS Radiated Emissions Radiated Emissions TA = 25°C, unless otherwise noted. PIN FUNCTIONS VIN (Bank 3): The VIN pin supplies current to the L TM8031’s internal regulator and to the internal power switch. This pin must be locally bypassed with an external, low ESR capacitor of at least 1μF . FIN (K3, L3): Filtered Input. This is the node after the input EMI fi lter . Use this only if there is a need to modify the behavior of the integrated EMI fi lter or if V IN rises or falls rapidly; otherwise, leave these pins unconnected. See the Applications Information section for more details. GND (Bank 2): Tie these GND pins to a local ground plane below the L TM8031 and the circuit components. Return the feedback divider (R ADJ) to this net. VOUT (Bank 1): Power Output Pins. Apply the output fi lter capacitor and the output load between these pins and GND pins. AUX (Pin H5): Low Current Voltage Source for BIAS. In many designs, the BIAS pin is simply connected to V OUT . The AUX pin is internally connected to VOUT and is placed adjacent to the BIAS pin to ease printed circuit board rout- ing. Although this pin is internally connected to V OUT , do not connect this pin to the load. If this pin is not tied to BIAS, leave it fl oating. BIAS (Pin H4): The BIAS pin connects to the internal power bus. Connect to a power source greater than 2.8V . If the output is greater than 2.8V , connect this pin to AUX. If the output voltage is less, connect this to a voltage source between 2.8V and 25V . Also, make sure that BIAS + V IN is less than 56V . RUN/SS (Pin L5): Pull RUN/SS pin to less than 0.2V to shut down the L TM8031. Tie to 2.5V or more for normal operation. If the shutdown feature is not used, tie this pin to the V IN pin. RUN/SS also provides a soft-start function; see the Applications Information section. RT (Pin G7): The RT pin is used to program the switching frequency of the L TM8031 by connecting a resistor from this pin to ground. The Applications Information section of the data sheet includes a table to determine the resistance value based on the desired switching frequency. Minimize capacitance at this pin. SHARE (Pin H7): Tie this to the SHARE pin of another L TM8031 when paralleling the outputs. FREQUENCY (MHz) EMISSIONS LEVEL (dBμV/m) VIN = 36V VOUT = 10V AT 1A 800

SYNC (Pin L6): This is the external clock synchronization input. Ground this pin for low ripple Burst Mode® operation at low output loads. Tie to a stable voltage source greater than 0.7V to disable Burst Mode operation. Do not leave this pin fl oating. Tie to a clock source for synchroniza- tion. Clock edges should have rise and fall times faster than 1μs. See Synchronization section in Applications Information. PGOOD (Pin K7): The PGOOD pin is the open-collector output of an internal comparator . PGOOD remains low until the ADJ pin is within 10% of the fi nal regulation voltage. The PGOOD output is valid when V IN is above 3.6V and RUN/SS is high. If this function is not used, leave this pin fl oating. ADJ (Pin J7): The L TM8031 regulates its ADJ pin to 0.79V . Connect the adjust resistor from this pin to ground. The value of R ADJ is given by the equation: R VADJ OUT = 196 71 07 9 where RADJ is in kΩ.

The L TM8031 is a standalone nonisolated step-down switching DC/DC power supply. It can deliver up to 1A of DC output current with only bulk external input and output capacitors. This module provides a precisely regulated output voltage programmable via one external resistor from 0.8VDC to 10VDC. The input voltage range is 3.6V to 36V . Given that the L TM8031 is a step-down converter , make sure that the input voltage is high enough to support the desired output voltage and load current. A simplifi ed Block Diagram is given on the previous page. The L TM8031 is designed with an input EMI fi lter and other features to make its radiated emissions compliant with several EMC specifi cations including EN55022 class B. Compliance with conducted emissions requirements may be obtained by adding a standard input fi lter . The L TM8031 contains a current mode controller , power switching element, power inductor , power Schottky diode and a modest amount of input and output capacitance. The L TM8031 is a fi xed frequency PWM regulator . The switch- ing frequency is set by simply connecting the appropriate resistor value from the RT pin to GND. An internal regulator provides power to the control circuitry. The bias regulator can draw power from the V IN pin, but if the BIAS pin is connected to an external voltage higher than 2.8V , bias power will be drawn from the external source (typically the regulated output voltage). This improves effi ciency. The RUN/SS pin is used to place the L TM8031 in shutdown, disconnecting the output and reducing the input current to less than 1μA. To further optimize effi ciency, the L TM8031 automatically switches to Burst Mode operation in light load situations. Between bursts, all circuitry associated with controlling the output switch is shut down reducing the input supply cur- rent to 50μA in a typical application. The oscillator reduces the L TM8031’s operating frequency when the voltage at the ADJ pin is low. This frequency foldback helps to control the output current during start-up and overload. The L TM8031 contains a power good comparator which trips when the ADJ pin is at 90% of its regulated value. The PGOOD output is an open-collector transistor that is off when the output is in regulation, allowing an external resistor to pull the PGOOD pin high. Power good is valid when the L TM8031 is enabled and V IN is above 3.6V . For most applications, the design process is straight forward, summarized as follows: 1. Look at Table 1 and fi nd the row that has the desired input range and output voltage. 2. Apply the recommended C IN, C OUT, R ADJ and R T values. 3. Connect BIAS as indicated. As the integrated input EMI fi lter may ring in response to an application of a step input voltage, a bulk capacitance, series resistance or some clamping mechanism may be required. See the Hot-Plugging Safely section for details. While these component combinations have been tested for proper operation, it is incumbent upon the user to verify proper operation over the intended system’s line, load and environmental conditions. Capacitor Selection Considerations The C IN and C OUT capacitor values in Table 1 are the minimum recommended values for the associated oper- ating conditions. Applying capacitor values below those indicated in Table 1 is not recommended, and may result in undesirable operation. Using larger values is generally acceptable, and can yield improved dynamic response, if it is necessary. Again, it is incumbent upon the user to verify proper operation over the intended system’s line, load and environmental conditions. Ceramic capacitors are small, robust and have very low ESR. However , not all ceramic capacitors are suitable. X5R and X7R types are stable over temperature and applied voltage and give dependable service. Other types, includ- ing Y5V and Z5U have very large temperature and voltage coeffi cients of capacitance. In an application circuit they
