FP5208-Non-Synchronous PWM Boost Controller General Description The FP5208 and FP5208B are boost topology switching regulator for wide operating voltage applications. They provide built-in gate driver pin for driving external N-MOSFET. The non-inverting input of error amplifier connects to a 0.6V precision reference voltage. They have programmable soft start time and PWM frequency set by external capacitors and resistors. FP5208B has programmable current detection and over current protection set by external resistors. The FP5208B is available in the small footprint DFN-12L package to fit in space-saving PCB layout for application fields. Features Wide Supply Voltage Operating Range: 2.5V to 24V Precision Feedback Reference Voltage: 0.6V (±2%) Shutdown Current: <1μA Programmable PWM Frequency: 100KHz~1000KHz Programmable Soft Start Function (SS) Light Load Detection / FP5208B Programmable Over Current Protection (OCP) / FP5208B Over Temperature Protection (OTP) Package: SOP-8L(EP) / FP5208, DFN-12L / FP5208B Applications Chargers LCD Displays Handheld Devices Portable Products
