onsemi FAN53745
The FAN53745 is a low quiescent current step−down DC/DC converter that delivers a regulated output voltage from an input supply of 2.3 V to 5.5 V. The combination of built−in power transistors, synchronous rectification, and a tiny solution size make the device ideal for portable applications. The converter normally operates in PWM Mode at a typical fixed−frequency of 3.33 MHz.DESCRIPTION
At moderate and light loads, the device will transition into PFM Mode to maintain high efficiency and excellent transient response. Additionally, a low power Shutdown Mode reduces power consumption when the device is disabled. The FAN53745 is available in 6−bump, 0.4 mm pitch, Wafer−Level Chip−Scale Package (WLCSP).FEATURES
