MP4420A

High-Efficiency 2A, 36V, FCCM Mode, Synchronous Step Down Converter with PG and Ext. Sync Synchronous Step-Down Switcher

Datasheet

Description

The MP4420A is a high-efficiency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very compact solution that achieves 2A of continuous output current with excellent load and line regulation over a wide input supply range. The MP4420A uses synchronous mode operation to achieve higher efficiency over the output current load range. Current-mode operation provides fast transient response and eases loop stabilization. Full protection features include over-current protection (OCP) and thermal shutdown. The MP4420A requires a minimal number of readily available, standard, external components and is available in a compact, 8-pin, TSOT23 package.

The EV4420A-J-00A is an evaluation board designed to demonstrate the capabilities of the MP4420A/MPQ4420A, a high-frequency, synchronous, rectified, step-down switch-mode converter with built-in power MOSFETs.

The MP4420A/MPQ4420A offers a very compact solution that can achieve up to 2A of continuous output current (I_OUT), with excellent load and line regulation across a wide input voltage (V_IN) supply range. The device provides synchronous mode for higher efficiency across the I_OUT load range.

Current mode provides fast transient response and eases loop stabilization. Full protection features include over-current protection (OCP) and thermal shutdown.

The EV4420A-J-00A is assembled and tested with a TSOT23-8 package.
