MP2349 - Synchronous Buck Converter

Description

The MP2349 is a fully integrated, highfrequency, synchronous, rectified, step-down switch-mode converter.

It offers a very compact solution to achieve up to 6.5A of continuous output current (IOUT) and 7.5A of peak output current (IOUT_MAX) across a wide input voltage (VIN) range.

Features

  • include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and thermal shutdown. The MP2349 requires a minimal number of external components, and is available in a QFN-11 (2mmx2mm) package. MP2349 24V, 6.5A, Low-IQ, Synchronous Buck Converter with Mode Selection.

DESCRIPTION The MP2349 is a fully integrated, highfrequency, synchronous, rectified, step-down switch-mode converter. It offers a very compact solution to achieve up to 6.5A of continuous output current (IOUT) and 7.5A of peak output current (IOUT_MAX) across a wide input voltage (VIN) range. The MP2349 operates at high efficiency across a wide IOUT load range based on MPS’s proprietary switching loss reduction technology and internal, low on resistance (RDS(ON)) power MOSFETs. Adaptive constant-on-time (COT) control provides fast transient response and eases loop stabilization. The DC auto-tune loop combined with the remote differential sense provides good load and line regulation.
