LM5022MM

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

LM5022MM 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 to the startup regulator, operates from 6 V to 60 V.
2 FB input Feedback pin inverting input to the internal voltage error amplifier with 1.25-V reference.
3 COMP bidirectional Error amplifier output and PWM comparator input with control loop compensation components connected between this pin and the FB pin.
4 VCC power_out Output of the internal high-voltage linear regulator that must be bypassed to GND with a ceramic capacitor.
5 OUT output Output of MOSFET gate driver with 1-A peak current capability connected to the gate of the external MOSFET.
6 GND power_in System ground.
7 UVLO input Input undervoltage lockout connected to input voltage through resistor divider with 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 and synchronization input where external resistor to GND sets frequency or AC-coupled input accepts external clock synchronization.
10 SS input Soft-start pin with external capacitor to ground charged by 10-µA current source creating ramp voltage for regulator startup.
