LM3402HVMMX

Texas Instruments · LED Drivers · VSSOP-8-0.65mm

LM3402HVMMX from Texas Instruments, in a VSSOP-8-0.65mm. 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 SW output Switch pin; connect this pin to the output inductor and Schottky diode.
2 BOOT output MOSFET drive bootstrap pin; connect a 10-nF ceramic capacitor from this pin to SW.
3 DIM input Input for PWM dimming; a logic-level PWM signal on this pin enables and disables the MOSFET and reduces the average LED light output.
4 GND power_in Ground pin; connect to system ground.
5 CS input Current sense feedback pin; set the LED array current by connecting a resistor from this pin to ground.
6 RON input ON-time control pin; a resistor from this pin to VIN sets the regulator controlled ON-time.
7 VCC power_out Output of the internal 7-V linear regulator; bypass to ground with a minimum 0.1-µF ceramic capacitor with X5R or X7R dielectric.
8 VIN power_in Input voltage pin; nominal operating input range is 6 V to 42 V (LM3402) or 6 V to 75 V (LM3402HV).
