PT4205 Description
The PT4205 is a continuous conduction mode inductive step-down converter, designed for driving single or multiple serie connected LEDs efficiently from a voltage source higher than the total LED chain voltage. The device operates from an input supply between 5V and 30V and provides an externally adjustable output current of up to 1.2A. Depending upon the supply voltage and external ponents, the PT4205can provide...
