MP2223 - Step-Down Converter

General Description

The MP2223 is a dual-channel, synchronous, rectified, step-down, switch-mode converter with built-in, internal power MOSFETs.

The MP2223 offers a very compact solution that achieves 3A/2A of continuous output current over a wide input supply range.

Key Features

  • include hiccup mode overcurrent protection (OCP) and thermal shutdown. Other features include power-save mode (PSM) at light load and a separate enable control (EN) for power-sequence control. The MP2223 requires a minimal number of readily available, standard, external components and is available in a space saving 8-pin TSOT23 package.

MP2223 18V, Dual-Channel 3A/2A, 540kHz, Synchronous, Step-Down Converter in 8-Pin TSOT23 Package DESCRIPTION The MP2223 is a dual-channel, synchronous, rectified, step-down, switch-mode converter with built-in, internal power MOSFETs. The MP2223 offers a very compact solution that achieves 3A/2A of continuous output current over a wide input supply range. Two channels operate 180° out-of-phase to minimize the input capacitor and alleviate EMI. Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include hiccup mode overcurrent protection (OCP) and thermal shutdown. Other features include power-save mode (PSM) at light load and a separate enable control (EN) for power-sequence control.
