Monolithic Power Systems (MPS) MPM3824 Synchronous Step-Down Power Module
Monolithic Power Systems (MPS) MPM3824 Synchronous Step-Down Power Module has an integrated inductor. It achieves up to 2A of continuous output current (IOUT) across a 2.75V to 6V input voltage (VIN) range, with excellent load and line regulation. The MPM3824 works in advanced asynchronous modulation (AAM) mode at light loads, and it can switch to continuous conduction mode (CCM) at heavy loads with a small voltage ripple.
The output voltage (VOUT) can be regulated as low as 0.6V. Only feedback (FB) resistors, input capacitors (CIN), and output capacitors (COUT) are required to complete the design. The constant-on-time (COT) control scheme provides fast transient response, high efficiency, and eases loop stabilization.
Full protections include cycle-by-cycle current limiting, short-circuit protection (SCP) with hiccup mode, and thermal shutdown. The Monolithic Power Systems (MPS) MPM3824 requires a minimal number of readily available, standard, external components, and it is available in an ultra-small ECLGA-14 (2.5mm x 2.5mm x 1.2mm) package.
