MP2384CGG-Z

Fully integrated, high-frequency, synchronous, rectified, step-down switch-mode converter. The MP2384C offers a highly compact solution that achieves 4A of continuous output current. It operates at high efficiency over a wide output current load range based on MPS’s proprietary switching loss reduction technique and internal low RDS(ON) power MOSFETs. Adaptive constant-on-time (COT) control mode provides fast transient response and eases loop stabilization. The DC auto-tune loop combines with the remote differential sense to provide good load and line regulation. Full protection features include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP) and thermal shutdown. The converter requires a minimal number of external components and is available in a QFN-11 (2mmx2mm) package. Typical applications include security cameras, portable devices, XDSL devices, digital set-top boxes, flat-panel television and monitors, general purposes.
