一级代理 Mr.Zheng: QQ: 1094642907 fitipower integrated technology lnc. FP6717 5V, 3.1A, 550KHz High Efficiency Low Ripple Synchronous Step-Up Converter Description Features The FP6717 is a high efficiency, fixed frequency High Efficiency up to 90% 550KHz, current mode PWM boost DC/DC converter Low RDS(ON) Integrated Power MOSFET which could operate battery such as input voltage NMOS 39mΩ/PMOS 42mΩ down to 2.5V. The converter output voltage can be Wide Input Voltage Range: 2.5V to 5.25V adjusted to a maximum of 5.25V by an external Fixed 550KHz Switching Frequency resistor divider. Besides the converter includes a Low-Power Mode for Light Load Conditions 39mΩ N-channel MOSFET switch and ±2.0% Voltage Reference Accuracy 42mΩP-channel synchronous rectifier. So no Adjustable Current Limit external Schottky diode is required and could get PMOS Current Limit for Short Circuit Protection better efficiency near 90%. Low Quiescent Current Input Under Voltage Lockout The converter is based on a fixed frequency, current Internal Compensation Function mode, pulse-width-modulation PWM controller that Built-In Soft Start Function goes automatically into PSM mode at light load. Over-Temperature Protection with Auto Recovery Output Overvoltage Protection When converter operation into discontinuous mode,
