1 FP6293 1 MHz, Step-Up Current Mode PWM Converter This datasheet contains new product information. Feeling Technology reserves the rights to modify the product specification without notice. No liability is assumed as a result of the use of this product. No rights under any patent accompany the sales of the product. Website: Rev. 1/12 General Description The FP6293 is a Current mode boost DC-DC converter. Its PWM circuitry with built-in power MOSFET make this regulator highly power efficient. The internal compensation network also minimizes as much as 6 external component counts. The non-inverting input of error amplifier connects to a precision reference voltage and internal soft-start function can reduce the inrush Current .

2 The FP6293 is available in the DFN-6L/DFN-8L package and provides space-saving PCB for the application fields. Features Adjustable Output up to 12V Internal Fixed PWM frequency: Precision Feedback Reference Voltage: ( 2%) Internal , , 16V Power MOSFET Shutdown Current : A Over Temperature Protection Adjustable Over Current Protection: ~ Package: DFN-6L, DFN-8L Applications Chargers LCD Displays Digital Cameras Handheld Devices Portable Products Typical Application Circuit FP6293 This datasheet contains new product information.
