LM5642X - 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.
