FAN49103 Datasheet | onsemi

Regulator - TinyPowerE, Buck-Boost, 2.5 A, I2C 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. The output voltage and operation mode of the regulator can be programmed through an I2C interface. At moderate and light loads, Pulse Frequency Modulation (PFM) is used to operate the device in power- save mode to...
