Product details

1.5 A buck LED driver with PWM dimming

The LM3406MH/NOPB: The integrated switch and PWM dimming input make it a single-chip solution for automotive exterior lighting and industrial luminaire designs where the input bus sees cold-crank dips and load-dump transients.

Switching frequency and thermal envelope

The oscillator runs from 10 kHz to 1 MHz, letting the designer balance inductor size against switching losses.
