Product details

Boost LED driver for backlight strings

The BD9422EFV-E2: The BD9422EFV- is a DC-DC boost regulator with integrated switch, designed to drive up to six LED channels at 400 mA each for backlight applications. Switching at 500 kHz, the converter uses a small inductor and ceramic output capacitor — the inductor ripple current stays manageable without pushing core losses into the thermal budget.

Input range and dimming flexibility

Dimming is supported in both analog and PWM modes — analog sets the LED current level continuously, while PWM dimming controls brightness by duty cycle, avoiding colour shift at low currents.
