1. Describe

MP2451DJ-LF-ZX is an integrated high frequency (2MHz) step-down switching regulator Internal high-side high-voltage power MOSFETs. It provides a single 0.6A (or lower) efficient Output with current mode control for fast cycling Reply. Wide Input Range from 3.3V to 36V Adapt to all kinds of blood pressure Applications in the automotive input environment. One 3µA Shutdown Mode Quiescent Current Enable Use in battery powered applications. High power conversion efficiency over a wide range The load range is achieved by scaling down Switching frequency at light load conditions Reduce switching and gate drive losses. Frequency Foldback Helps Prevent Inductance Current runaway during startup. hot Shutdown provides reliable fault tolerance Operation. The MP2451 is cost-effective in SOT23-6 and TSOT23-6 packages.
