Texas Instruments LM5176-Q1 Synchronous 4-Switch Buck-Boost DC/DC Controller is capable of regulating the output voltage at, above, or below the input voltage. The LM5176-Q1 operates over a wide input voltage range of 4.2V to 55V (60V absolute maximum) to support a variety of applications. The LM5176-Q1 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.
