Texas Instruments LM5175
the LM5175 with the WEBENCH Power Designer 2 Applications 3 Description The LM5175 is a synchronous four-switch buck-boost DC/DC controller capable of regulating the output voltage at, above, or below the input voltage. The LM5175 operates over a wide input voltage range of 3.5 V to 42 V (60 V maximum) to support a variety of applications. The LM5175 employs current-mode control both in buck and boost modes of operation for superior load and line regulation.| Part No. | LM5175 |
