LM5642XMHX/NOPB General Description

The LM5642XMHX/NOPB is a versatile current mode synchronous buck regulator controller that offers precise control and efficient operation. Operating at a switching frequency of 200kHz for the LM5642 and 375kHz for the LM5642X, this controller ensures reduced input RMS ripple current, minimizing the required input capacitance. Users have the flexibility to synchronize the switching frequency to an external clock within a specified range. Additionally, the dual-phase, single output regulator capability allows for increased power delivery efficiency
