Texas Instruments LM5176
the LM5176 with the WEBENCH Power Designer 2 Applications • Industrial PC power supplies • USB power delivery • Battery-powered systems • LED lighting VIN 3 Description The LM5176 is a synchronous four-switch buck-boost DC/DC controller capable of regulating the output voltage at, above, or below the input voltage. The LM5176 operates over a wide input voltage range of 4.2 V to 55 V (60-V absolute maximum) to support a variety of applications. The LM5176 uses current-mode control both in buck and boost modes of operation for superior load and line regulation.| Part No. | LM5176 |
