MP2388  
1A, 21V, 2MHz, High-Efficiency,  
Synchronous, Step-Down Converter  
in Ultra-Thin QFN Package  
DESCRIPTION  
FEATURES  
The MP2388 is a high-frequency, synchronous,  
rectified, step-down, switch-mode converter  
with built-in, internal power MOSFETs. It offers  
a very compact solution that achieves 1A of  
continuous output current over a wide input  
supply range with excellent load and line  
regulation. Current mode operation provides  
fast transient response and eases loop  
stabilization.  
Wide 4.5V to 21V Operating Input Range  
1A Load Current  
110/50Low RDS(ON) Internal Power  
MOSFETs  
Low Quiescent Current  
High-Efficiency Synchronous Mode  
Operation  
Fixed 2MHz Switching Frequency  
AAM Power Save Mode  
Internal Soft Start  
Over-Current Protection (OCP) and Hiccup  
Thermal Shutdown  
Output Adjustable from 0.8V  
Available in a QFN-8 (1.5mmx2.5mm)  
Package  
Full protection features include over-current  
protection (OCP) and thermal shutdown.  
The MP2388 requires a minimum number of  
readily  
available,  
standard,  
external  
components and is available in a space-saving  
QFN-8 (1.5mmx2.5mm) package.  
APPLICATIONS  
Notebook Systems and I/O Power  
Digital Set-Top Boxes  
Flat-Panel Televisions and Monitors
