 FP7218-Non-Synchronous PWM Boost Converter for LED Driver  DataSheet General DescriptionThe FP7218 is a boost topology switching regulators for LED driver. Its built-in 80mΩ power MOSFET makes this regulator highly power efficient. The non-inverting input of error amplifier connects to a default 0.104V reference voltage. It has programmable soft start time set by external capacitor, and over voltage protection set by external resistor. The LED current can be adjusted by an external signal connecting to the EN pin. EN pin accepts either a DC voltage or a PWM signal. The
 PWM signal filter components are contained within the chip.
