FAN4868UC33X中文资料3 MHz, Synchronous Regulator数据手册ONSEMI规格书

描述 Description

The FAN4868 is a low−power boost regulator designed to provide a regulated 3.3 V output from a single cell Lithium or Li−Ion battery. Output voltage options are fixed at 3.3 V with a guaranteed maximum load current of 200 mA at VIN = 2.3 V and 300 mA at VIN = 3.3 V. Input current in Shutdown Mode is less than 1 μA, which maximizes battery life.
Light−load PFM operation is automatic and “glitch−free”. The regulator maintains output regulation at no−load with as low as 37 μA quiescent current.
The combination of built−in power transistors, synchronous rectification, and low supply current make the FAN4868 ideal for battery powered applications.
The FAN4868 is available in 6−bump 0.4 mm pitch Wafer−Level Chip Scale Package (WLCSP).
