    PULAN TECHNOLOGY CO., LIMITED PS7516 2.5A High Efficiency Synchronous PWM Boost Converter Description The PS7516 is a high efficiency, fixed frequency 550KHz, current mode PWM boost DC/DC converter which could operate battery such as input voltage down to 1.9V. 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 936%. The converter is based on a fixed frequency, current mode, pulse-width-modulation PWM controller that goes automatically into PSM mode at light load.
