FAN49101 Datasheet Buck-Boost Regulator

Manufacturer: onsemi

Overview: DATA SHEET www.onsemi.com Regulator - Buck-Boost, TinyPowerE, I2C, 2 A, 1.8 MHz WLCSP20 2.015x1.615x0.

General Description

The FAN49101 is a high efficiency buck−boost switching mode regulator which accepts input voltages either above or below the regulated output voltage.

Using full−bridge architecture with synchronous rectification, the FAN49101 is capable of delivering up to 2 A while regulating the output at 3.4 V.

The FAN49101 exhibits seamless transition between step−up and step−down modes reducing output disturbances.
