FP6755S6CTR

Fitipower Integrated Tech · LED Drivers · SOT-23-6

FP6755S6CTR from Fitipower Integrated Tech, 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 SW output Switch node pin. Drain of the internal N-MOS power switch; connect the boost inductor and Schottky diode here. Absolute max 34V; internal RDS(on) ~0.25Ω, current limit ~2A. Minimize trace area to reduce EMI.
2 GND power_in Ground pin. Connect directly to the local ground plane, close to the input capacitor return.
3 FB input Feedback pin. Regulates to a 195mV (typ, 185-205mV) reference by sensing the voltage across the LED current-set resistor from the cathode of the lowest LED to GND. LED current = 195mV / RFB. Absolute max 6V; input bias current -300nA.
4 EN input Enable and PWM dimming control input. Logic high (>1.4V) enables the device; logic low (<0.3V) forces shutdown. Also accepts a 100Hz-50kHz PWM signal (amplitude >1.5V) for direct LED dimming. Absolute max 6V.
5 OVP input Over-voltage protection sense input. Monitors the LED string output voltage for open-circuit protection; shuts off switching when VOUT rises above ~29V (28V min). Connect to the top of the LED string (VOUT).
6 VIN power_in Input supply pin. Operating range 2.5V to 5.5V (absolute max 6V). Must be locally bypassed with a ceramic capacitor (10µF X5R/X7R typical) close to the pin.
