LM5020MM-2

Texas Instruments · DC-DC Converters · VSSOP-10-0.5mm

LM5020MM-2 from Texas Instruments, in a VSSOP-10-0.5mm. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in High-voltage power supply input to the start-up regulator with operating range of 13V to 100V.
2 FB input Inverting input of the internal error amplifier with internally connected 1.25V non-inverting reference input.
3 COMP output Output of the error amplifier serving as input to the PWM comparator; includes internal 5kΩ pull-up resistor for opto-coupler biasing.
4 VCC power_out 7.7V regulated output of the internal high voltage series pass regulator; internal regulator shuts down if external voltage exceeds regulation setpoint.
5 OUT output PWM controller gate driver output with 1A peak current source/sink capability.
6 GND power_in Ground return.
7 UVLO input Under-voltage lockout sense pin with 1.25V threshold; external resistor divider from VIN sets shutdown level; 20µA internal current source provides hysteresis.
8 CS input Current sense input for current mode control and cycle-by-cycle over-current protection; 0.5V threshold triggers output shutdown; 50ns leading-edge blanking after OUT transition.
9 RT/SYNC input Oscillator timing resistor pin where external resistor to GND sets switching frequency; also accepts synchronization pulses from external clock.
10 SS passive Soft-start capacitor connection charged by internal 10µA current source to control soft-start ramp rate.
