LED Driver for Lighting Series

Electrolytic Capacitor Free

Buck Converter LED Driver

BD555A1AFV

●General Description

●Features

BD555A1AFV is a LED driver best for LED lighting

applications. It supports dimming. Constant current

switching controller for AC/DC buck converter is

accumulated inside. By choosing external MOS

Transistor, small～large power of LED can be driven.

The driver is adoptable to a wide range of lighting from

small light such as spotlights to large one like base

lights.

With digital power control, the average value of LED

current is stably adjustable to requesting current. By

only primary sense resistor, LED current is available to

feedback LED current is useful without feedback

circuits, reduce parts. Input characteristics and output

characteristics is good by precisely digital power

control.

■

Highly efficient Buck AC/DC converter

Primary control without feedback circuit
