LOWPOWER · AC-DC Controllers And Regulators · SOT-23-6

LP3310B6F from LOWPOWER, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 LX output Output switching node. Drain of the internal 100mΩ, 4A N-MOSFET switch. Connects to the boost inductor and Schottky diode. Absolute maximum voltage -0.3V to 33V.
2 GND power_in Ground pin. Should be connected to a strong ground plane for heat sinking and noise protection.
3 FB input Feedback reference voltage pin. Series-connect a current sense resistor between the WLED string and ground; feedback voltage is regulated to 250mV typ (240-260mV). ILED = 250mV / R1. Feedback input current typ 50nA.
4 EN input Chip enable (active high) and PWM dimming input. VIH=1.4V min, VIL=0.4V max. High-impedance pin - connect a 100kΩ pull-down to GND when the control signal may float. Accepts PWM dimming from 100Hz to 100kHz down to 1% duty cycle. Also triggers over-voltage-protection sensing.
5 NC unconnected No connect. Leave floating or tie as convenient for PCB routing.
6 VIN power_in Supply input voltage pin. Operating range 2.7V to 24V; absolute maximum 30V. Bypass with a 1uF (10uF recommended in typ. application) ceramic capacitor to GND to reduce input noise. UVLO 2.5V typ with 0.3V hysteresis.
