MPM3824数据手册MPS中文资料规格书

描述 Description

The MPM3824 is a synchronous, step-down power module with 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 MPM3824 requires a minimal number of readily available, standard, external components, and it is available in an ultra-small ECLGA-14 (2.5mmx2.5mmx1.2mm) package.
