FP6716
5V, 8A, 550KHz High Efficiency Low Ripp8l5eT Synchronous Step-Up Converter
Description
The FP6716 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 0.
05Ω N-channel
MOSFET switch and 0.
08Ω P-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.
