Product Description

The MP2329 is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter. The MP2329 offers a super-compact solution that achieves 6.5A of continuous output current and 7.5A of peak output current over a wide input supply range. The MP2329 operates at high efficiency over a wide output current load range based on MPS’s proprietary switching loss reduction technique and internal low RDS(ON) power MOSFETs. Adaptive constant-on-time (COT) control mode 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. Full protection features include over-current protection (OCP), over-voltage protection (OVP), under-voltage protection (UVP), and thermal shutdown. The converter requires a minimal number of external components and is available in a QFN-11 (2mmx2mm) package.

Kit details

The EV2329-G-00A is an evaluation board for MP2329, a fully integrated high frequency synchronous rectified step-down switch mode converter. It offers super compact solution to achieve 6.5A continuous output current and 7.5A peak output current over a wide input supply range.

The MP2329 operates at high efficiency over a wide output current load rang based on MPS proprietary switching loss reduction tech and internal Low Ron Power MOSFETs. Adaptive Constant-On-Time (COT) control mode 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.

Full protection features include OCP, OVP, UVP and thermal shut down.

The converter requires minimum number of external components and is available in QFN 2mmx2mm package.
