FP5205-Non-Synchronous PWM Boost Controller


FP5205-Non-Synchronous PWM Boost Controller DataSheet

General Description
    The FP5205 is a boost topology switching regulator for wide operating voltage applications. It provides built-in gate driver pin for driving an 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 FP5205 has internal soft start and programmable over current protection set by external resistance.
    The FP5205 is available in the small footprint SOT23-6L 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 Current Protection Function (OCP)
 Over Voltage Protection
 Package: SOT23-6L
 Duty Cycle: PWM/PFM Switching Control Circuit (15%~90%)

Applications
 Chargers
 LCD Displays
 Digital Cameras
 Handheld Devices
 Portable Products
