MP2384C

24V, 4A, Low I_Q,

Synchronous Buck Converter with

Forced Continuous Conduction Mode (CCM)

DESCRIPTION

FEATURES

The MP2384C is a fully integrated, high-

frequency, synchronous, rectified, step-down,

switch-mode converter. The MP2384C offers a

highly compact solution that achieves 4A of

continuous output current.



Wide 4.5V to 24V Operating Input Range

105μA Low Quiescent Current

4A Continuous Output Current

Adaptive Constant-On-Time (COT) Control

for Fast Transient



DC Auto-Tune Loop

Low R_DS(ON)Internal Power MOSFETs

Forced PWM Operation

Power Good (PG) Indication

Fixed 700kHz Switching Frequency

Stable with POSCAP and Ceramic

Capacitors

1% Reference Voltage

Internal Soft Start (SS)

Output Discharge

OCP, OVP, UVP, and Thermal Shutdown

with Auto-Retry

The MP2384C 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 mode

provides fast transient response and eases loop

stabilization. The DC auto-tune loop combines

with the remote differential sense to provide

good load and line regulation.



Full protection features include over-current

protection (OCP), over-voltage protection

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

thermal shutdown.



Available in a QFN-11 (2mmx2mm)

Package

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 Television and Monitors
