LM34936 Overview
The LM34936 is a synchronous four-switch buckboost DC/DC controller capable of regulating the output voltage at, above, or below the input voltage. The LM34936 operates over a wide input voltage range of 4.2 V to 30 V (42-V ) to support a variety of applications. The LM34936 employs current-mode control both in buck and boost modes of operation for superior load and line regulation.
