HT3302ARTZ

HTCSEMI · LED Drivers · SOT-23-6

HT3302ARTZ from HTCSEMI, in a SOT-23-6. 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 Power switch output of the boost converter; the datasheet gives an absolute maximum VSW of -0.5 to 40 V and an output voltage range of VIN to 35 V.
2 GND power_in Ground; the datasheet recommends connecting it to a strong ground plane for heat sinking and noise protection.
3 FB input Feedback input regulated to 300 mV (VFB 291 to 309 mV); the LED current is set as I = 300 mV / R1 with an external sense resistor.
4 EN input Chip enable with VEN_H minimum 1.5 V and VEN_L maximum 0.4 V, which also accepts PWM dimming up to 200 kHz.
5 NC unconnected Not connected.
6 IN power_in Power supply input with an operating range of 2.5 to 7.5 V and an absolute maximum of -0.3 to 8 V.
