General 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 more than tens of watts of output power.

Key Features

  • Simple low parts count Wide input voltage range: 5V to 30V Up to 1.2A output current Single pin on/off and brightness control using DC voltage or PWM Typical 3% output current accuracy Inherent open-circuit LED protection High efficiency (up to 97%) Hysteretic Control: No Compensation Adjustable Constant LED Current Soft over temperature protection ESOP8 package for large output power.
