www.DataSheet.co.kr A Product Line of Diodes Incorporated ZXLD1352 350mA LED driver with internal switch and enhanced PWM dimming range Description The ZXLD1352 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 350mA. Depending upon supply voltage and external components, this can provide up to 8 watts of output power. The ZXLD1352 includes the output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current.
