📥 Download Datasheet

General Description

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.

The DIM input allows a wide range of dimming control for LED backlighting or LED lighting.
