MP2329

24V, 6.5A, Low I_Q,

Synchronous, Buck Converter

The Future of Analog IC Technology

DESCRIPTION

FEATURES



Wide 4.5V to 24V Operating Input Range

105μA Low Quiescent Current

6.5A Continuous Output Current

7.5A Peak Output Current

Adaptive Constant-On-Time (COT) Control

for Fast Transient

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.



DC Auto-Tune Loop

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 R_DS(ON)power MOSFETs.

Low R_DS(ON)Internal Power MOSFETs

Proprietary Switching Loss Reduction

Technique



Power Good (PG) Indication

Fixed 700kHz Switching Frequency

Stable with POSCAP and Ceramic

Capacitors

Internal Soft Start (SS)

Output Discharge

OCP, OVP, UVP, and Thermal Shutdown

with Auto-Retry

Available in a QFN-11 (2mmx2mm)

Package

The MPL-AL6050 Inductor Series Matches

Best Performance

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.

APPLICATIONS



Security Cameras

Portable Devices, XDSL Devices

Digital Set-Top Boxes

Flat-Panel Televisions and Monitors

General Purposes



All MPS parts are lead-free, halogen-free, and adhere to the RoHS

directive. For MPS green status, please visit the MPS website under

Quality Assurance. “MPS” and “The Future of Analog IC Technology” are
