FP6717 5V, 3.1A, 550KHz High Efficiency Low Ripple Synchronous Step-Up Converter Description The FP6717 is a high efficiency, fixed frequency 550KHz, current mode PWM boost DC/DC converter which could operate battery such as input voltage down to 2.5V. The converter output voltage can be adjusted to a maximum of 5.25V by an external resistor divider. Besides the converter includes a 39mΩ N-channel MOSFET switch and 42mΩP-channel synchronous rectifier. So no external Schottky diode is required and could get better efficiency near 90%. The converter is based on a fixed frequency, current mode, pulse-width-modulation PWM controller that goes automatically into PSM mode at light load.
