MPM3612 Datasheet | Monolithic Power Systems

DESCRIPTION The MPM3612 is a synchronous, rectified, stepdown, switch-mode power module with built-in internal power MOSFETs and high light-load efficiency. The MPM3612 has an ultra-low 5µA quiescent current (IQ). The MPM3612 offers a very pact solution that can achieve up to 1A of continuous output current (IOUT), with excellent load and line regulation across a wide input supply range. The MPM3612 switching edge is optimized for EMI reduction. Constant-on-time (COT) control enables seamless mode transition and fast load transient response. Protection features include over-current protection (OCP), over-voltage protection (OVP), and thermal shutdown. The MPM3612 requires a minimal number of readily available, standard external ponents, and is available in a space-saving LGA (3mmx3mmx2mm) package.
