MP2348

High-Efficiency, 4A, 24V, 650kHz,

Synchronous Step-Down Converter

in SOT583 Package

DESCRIPTION

FEATURES

The MP2348 is a fully integrated, high-

frequency, synchronous, rectified, step-down,

switch-mode converter with internal power

MOSFETs. It offers a compact solution to

achieve 4A of continuous output current across

a wide input range, with excellent load and line

regulation. The MP2348 has synchronous

mode operation for higher efficiency across the

output current load range.



Wide 4.2V-to-24V Operating Input Range

75mΩ/40mΩ Low R_DS(ON)Internal Power

MOSFETs

200µA Low I_Q

High-Efficiency Synchronous Mode

Operation



Selectable Forced PWM, Auto-PFM/PWM

and Ultrasonic Mode



Fast Load Transient Response

650kHz Switching Frequency

Configurable Soft-Start Time

Over-Current Protection and Hiccup Mode

Pre-Biased Start-Up

Thermal Shutdown

Available in an SOT583 (1.6mmx2.1mm)

Package

Constant-on-time (COT) control provides fast

transient response and easy loop design, as

well as tight output regulation.

Full protection features include short-circuit

protection (SCP), over-current protection (OCP),

under-voltage protection (UVP), and thermal

shutdown.



The MPL-AL6050 Inductor Series Matches

Best Performance

The MP2348 requires a minimal number of

readily

available,

standard

external

components, and is available in a space-saving

SOT583 (1.6mmx2.1mm) package.

APPLICATIONS



Game Consoles

Digital Set-Top Boxes

Flat-Panel Televisions and Monitors
