FP7203-Constant Current Switching Regulator for White LED DataSheet
The FP7203 is a Boost DC-DC converter specifically designed to drive white LEDs with constant current. It provides built-in 140mΩ/4.5A/18V N-MOSFET. The non-inverting input of error amplifier connects to a 0.25V precision reference voltage and internal soft-start function can reduce the inrush current. Over voltage protection set by external resistor. DC voltage and PWM signal dimming can be adjusted by an external circuit connecting to the FB pin.
The FP7203 is available in the SOP-8L(EP) package and provides space-saving PCB for the application fields.
