MP2384C Synchronous Buck Converter with Forced CCM

MPS’ 24 V, 4 A, low IQ converter requires a minimal number of external components and is available in a QFN-11 (2 mm x 2 mm) package

MPS’ MP2384C fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter with forced continuous conduction mode (CCM) offers a highly compact solution that achieves 4 A of continuous output current. The device 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 combines with the remote differential sense to provide 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.
