FAN49101 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.
