FP1207元件值計算

General Description
    The FP1207 is boost topology switching regulator for wide operating voltage applications. It provides built-in gate driver pin for driving external N-MOSFET. The non-inverting input of error amplifier connects to a 1.2V precision reference voltage. It has programmable switching frequency set by external resistor, and programmable inductor peak current limit connects a resistor from CS to GND. Current mode control and external compensation network make is easy and flexible to stabilize the system.
    The FP1207 is available in the small footprint SOP-8L(EP) package to fit in space-saving PCB layout for application fields.
