The HT7963 is a high efficiency boost converter with a fixed oscillator frequency for LED backlighting and LED lighting application.

The white LED current is setup using an external current setting resistor, which has a low feed-back voltage of only 0.3V.

Integrated high power boost DC-DC controller.
Wide input voltage range from 9V to 30V.
High Voltage Gate-Drive provides lower RDS(ON) and higher efficiencies.
Dimming frequency from 100Hz to 1kHz.
0.3V LED feedback current sensing voltage with ±3% tolerance.
Device protection features include: Soft-start, OCP, UVLO, OVP, OTP and output short protection.
OSP.
LED protection: LED Open/Short Protection.
