FP5209

FP5209 Non-Synchronous PWM Boost Controller General Description The FP5209 is a boost topology switching regulator for wide operating voltage applications. It provides built-in gate driver pin, EXT pin, for driving the external N-MOSFET. The internal compensation network minimizes external component counts, and the non-inverting input of error amplifier connects to a 0.6V precision reference voltage. The FP5209 have internal soft start function. The FP5209 is available in the small footprint SOT23-5L package to fit in space-saving PCB layout for miscellaneous application fields. Features  Wide Supply Voltage Operating Range: 2.4 to 5.5V  Precision Feedback Reference Voltage: 0.6V (±2%)  Shutdown Current: <1μA  Internal Fixed PWM frequency: 550KHz  Internal Soft Start Function :7ms (SS)  Over Voltage Protection  Package: SOT23-5L  Duty Cycle: PWM/PFM Switching Control Circuit (15%~90%) Applications  Chargers  LCD Displays  Digital Cameras  Handheld Devices  Portable Products Typical Application Circuit VIN VOUT 1 FB 2 Vcc 3 ON/OFF EN GND EXT 5 FP5209 4 This datasheet contains new product information.
