FP5207应用介绍 Application Note
General Description The FP5207 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 FP5207 is available in the small footprint SOP-8L(EP) package to fit in space-saving PCB layout for application fields.
Features Start-up Voltage: 2.8V Wide Supply Voltage Operating Range: 5V to 24V Precision Feedback Reference Voltage: 1.2V (±2%) Shutdown Current: <3μA Programmable Switching Frequency: 100KHz~1000KHz Input Under Voltage Protection(UVP) Switching MOSFET Over Current Protection (OCP) Over Temperature Protection (OTP) Package: SOP-8L(EP)
