The SGM66057A is an internally compensated, 2.4MHz switching frequency, current mode, synchronous Boost switching converter. The output voltage is fixed at 5.0V. The SGM66057A implements a MODE pin to configure forced PWM mode or auto PFM mode at light loads. Its output is disconnected by the rectifier circuit during shutdown, with no input to output leakage.
Various protection features such as over-current, short-circuit and over-temperature are implemented to protect the device from various fault conditions.
The SGM66057A is available in a Green WLCSP1.26×1.21-9B package.
