SY7201ABC

Silergy Corp · LED Drivers · SOT-23-6

SY7201ABC from Silergy Corp, 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 power_out Inductor switching node. Connect the boost inductor between IN and LX. Absolute maximum rating 36V.
2 GND power_in Ground pin. Also serves as the case reference position for θJC measurement.
3 FB input Feedback pin. Connect a sense resistor R1 between FB and GND to program the output LED current: IOUT = 0.2V / R1 (VREF ≈ 200mV). FB input current ≈ 1µA max.
4 EN/PWM input Enable and PWM dimming control input. VENH ≈ 1.5V (rising), VENL ≈ 0.4V (falling). Absolute maximum 4V. Recommended PWM dimming frequency ≥ 20kHz.
5 OVP input Open-LED over-voltage protection sense pin. Output clamp voltage typ. 30V. Absolute maximum rating 36V.
6 IN power_in Input supply pin, 2.5V to 30V operating (absolute maximum 32V). Decouple to GND with a 1µF ceramic capacitor. UVLO threshold ≈ 2.4V with 0.1V hysteresis.
