Description
The FP6715 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 0.08Ω N-channel MOSFET switch and 0.12Ω P-channel synchronous rectifier. So no external Schottky diode is required and could get better efficiency near 93%.
The converter is based on a fixed frequency, current mode, pulse-width-modulation PWM controller that goes automatically into PSM mode at light load.
When converter operation into discontinuous mode, the internal anti-ringing switch will reduce interference and radiated electromagnetic energy.
The FP6715 is available in a space-saving SOT-23-6 package for portable application.
