LM5642 Datasheet (Texas Instruments) - Dual Synchronous Buck Converter

LM5642, Dual Synchronous Buck Converter

The LM5642 series consists of two current mode synchronous buck regulator controllers operating 180° out of phase with each other at a normal switching frequency of 200kHz for the LM5642 and at 375kHz for the LM5642X.

Out of phase operation reduces the input RMS ripple current, thereby significantly
