Description
The T6322 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 1.5A. Depending upon supply voltage and external components, this can provide up to 42 watts of output power. The T6322A includes the output switch and a high side output current sensing circuit, which uses an external resistor to set the nominal average output current.
