FP7218-Non-Synchronous PWM Boost Converter for LED Driver DataSheet
General Description The 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.
Features Wide Supply Voltage Operating Range: 2.5V to 24V Precision Feedback Reference Voltage: 0.104V (Default) Analog and Digital Dimming Control Shutdown Current: 6μA (Max.) Internal Fixed Switching Frequency: 300KHz Programmable Soft Start Function (SS) Programmable Over Voltage Protection (OVP) Over Temperature Protection (OTP) MOSFET: 100V/3A/80mΩ LED Voltage up to 75V Package: SOP-8L(EP)
