MP2386

24V, 8A, Low I_Q,

Synchronous Buck Converter

DESCRIPTION

FEATURES

The MP2386 is a fully integrated, high-

frequency, synchronous, rectified, step-down,

switch-mode converter. The MP2386 offers a

super-compact solution that achieves 8A of

continuous output current over a wide input

supply range.



Wide 4.5V to 24V Operating Input Range

105μA Low Quiescent Current

8A Continuous Output Current

Adaptive COT for Fast Transient

DC Auto-Tune Loop

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 Caps

Internal Soft Start (SS)

The MP2386 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.



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.

Output Discharge

OCP, OVP, UVP, and Thermal Shutdown

with Auto-Retry



Available in

Package

QFN-11 (2mmx2mm)

Full protection features include over-current

protection (OCP), over-voltage protection

(OVP), under-voltage protection (UVP), and

thermal shutdown.

The MPL-AL6050，MPL-AL4020 Inductor

Series Matches Best Performance

APPLICATIONS

The converter requires a minimal number of

external components and is available in a QFN-

11 (2mmx2mm) package.



Security Cameras

Portable Devices, XDSL Devices

Digital Set-Top Boxes

Flat-Panel Televisions and Monitors
