GENERAL DESCRIPTION
The T8300AD 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 4.5V and 30V and provides an externally adjustable output current of up to 1200mA. Depending upon supply voltage and external components, this can provide up to 29 watts of output power. The T8300AD includes the output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current. The T8300AD is available in SOP-8 Lead-free package.
