PRODUCT DESCRIPTION
The GLF8114 is a low quiescent current, peak current mode PWM synchronous step-down DC/DC converter. The device integrates switches capable of delivering an output current up to 4 A.
The GLF8114 operates over a wide input voltage range from 2.5 V to 5.5 V and runs in 1.3 MHz switching frequency to minimize the PCB and external components’ size. The GLF8114 can automatically switches between PWM in heavy load operation and PFM for light-load operation to minimize the switch loss.
