T8308 - TM Technology

T8308 PWM Control 800mA Step-Down Converter

The T8308 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage. The device operates from an input supply between 7V and 30V and provides an externally adjustable output current of up to 800mA. Depending upon supply voltage and external c.
