Image of MPS Monolithic Power Systems MP2384 Step-Down Converter The MPS Monolithic Power Systems MP2384 is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter. The MP2384 offers a super-compact solution that achieves 4 A of continuous output current over a wide input supply range.

The MP2384 operates at high efficiency over a wide output current load range based on MPS’ proprietary switching loss reduction technique and internal low R_DS(ON) power MOSFETs. Adaptive constant-on-time (COT) control mode provides fast transient response and eases loop stabilization. The DC auto-tune loop combined with the remote differential sense provides good load and line regulation.

Full protection features include overcurrent protection (OCP), overvoltage protection (OVP), undervoltage protection (UVP), and thermal shutdown. The converter requires a minimal number of external components and is available in a QFN-11 (2 mm x 2 mm) package.
