PS7516

PS7516 Wide Input Voltage Range: 2 5V to 5.5V Description The PS7516 is a high efficiency, fixed frequency 1MHz, 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. When converter operation into discontinuous mode, the internal anti-ringing switch will reduce interference and radiated electromagnetic energy. The PS7516 is available in a space-saving SOT-23-6 package for portable application. Features  High Efficiency up to 96% (When Vin = 4.2V)  Low RDS(ON) Integrated Power MOSFET  NMOS 80...
