LM34936 Buck-Boost Controller

Texas Instruments LM34936 Buck-Boost Controller is a synchronous four-switch buck-boost 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 4.2V to 30V (42V absolute maximum) 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. The switching frequency is programmed by an external resistor and can be synchronized to an external clock signal.
