M4001DLCC-3V3

The M4001 is a 0.7A fully integrated power module in LGA-8 package with step-down switching mode Power SoC (System on Chip) with integrated power MOSFETs, inductor and input decoupling capacitor inside. The input voltage is from 4.5V to 48V and the switching frequency is fixed at 1.6MHz. The M4001 provides high efficiency with Peak Current Control Mode. It works on PSM mode for light load and supports high duty cycle for low dropout. Also, M4001 is suitable for negative output. The M4001 can indicate faults with complete protection features, including over-load hiccup protection and over temperature shutdown protection.
