RT4526GJ6 from Richtek Tech, in a TSOT-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 power_out Switching node. Drain of the internal N-MOSFET; connects to the boost inductor and the anode of the external Schottky diode. Rated -0.3V to 50V absolute max; RDS(on) ~0.7Ω typ.
2 GND power_in Device ground return for the internal MOSFET source and analog/control circuitry.
3 FB input Feedback pin. LED current sense input; place resistor R_SET from FB to GND to program LED current (VREF = 300mV typ, 285-315mV). Also accepts PWM dimming signal.
4 EN input Chip enable, active high. VIH ≥ 1.4V enables the converter, VIL ≤ 0.5V shuts it down (I_SHDN ~1µA). Absolute max -0.3V to 6V.
5 VOUT power_in Boost output voltage sense pin used for over-voltage protection (OVP threshold 30V min). Connect to the boosted rail after the Schottky diode / output capacitor. Absolute max -0.3V to 46V.
6 VIN power_in Input supply, 2.5V to 5.5V operating range (absolute max -0.3V to 6V). Bypass with 2.2µF ceramic capacitor to GND. UVLO ≈ 2.2V typ.
