onsemi FAN4860
The FAN4860 is a low−power boost regulator designed to provide a regulated 3.3 V, 5.0 V or 5.4 V output from a single cell Lithium or Li−Ion battery. 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 FAN4860 ideal for battery powered applications.| Part No. | FAN4860 |

DESCRIPTION
Output voltage options are fixed at 3.3 V, 5.0 V, or 5.4 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 FAN4860 is available in 6−bump 0.4 mm pitch Wafer−Level Chip Scale Package (WLCSP) and a 6−lead 2 x 2 mm ultra−thin MLP package.FEATURES
