FAN49103 Datasheet Buck-boost Regulator

Manufacturer: onsemi

Overview: Regulator - TinyPowerE, Buck-Boost, 2.5 A, I2C FAN49103.

General Description

The FAN49103 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 FAN49103 is capable of delivering up to 2.5 A while regulating the output at 3.4 V.

The FAN49103 exhibits seamless transition between step−up and step−down modes reducing output disturbances.
