LM5022MME

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

LM5022MME 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 Source input voltage input to the startup regulator, operating from 6 V to 60 V.
2 FB input Inverting input to the internal voltage error amplifier, whose noninverting input connects to a 1.25-V reference.
3 COMP bidirectional Error amplifier output and PWM comparator input, with control loop compensation components connected between this pin and FB.
4 VCC power_in Output of the internal high-voltage linear regulator that must be bypassed to GND with a ceramic capacitor.
5 OUT output MOSFET gate driver output that connects to the external MOSFET gate and provides 1-A peak drive current capability.
6 GND power_in System ground.
7 UVLO input Input undervoltage lockout that sets start-up and shutdown levels through a resistor divider from the input voltage, with a 20-µA current source providing hysteresis.
8 CS input Current sense input for the switch current used for current mode control and current limiting.
9 RT/SYNC input Oscillator frequency adjust pin where an external resistor to GND sets the switching frequency, and which can also accept an AC-coupled synchronization clock.
10 SS input Soft-start pin where an external capacitor to ground is charged by a 10-µA current source to create a ramp controlling start-up.
