Preliminary T8306
PWM Control 36V Step-Down Controller
General Description
The T8306 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 36V and provides an externally adjustable output current of up to 3A. Depending upon supply voltage and external components, The T8306 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 T8306 is available in SOT23 Lead-free package.
