MP1496  
High-Efficiency, 2A, 16V, 500kHz  
Synchronous, Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP1496 is a high-frequency, synchronous,  
rectified, step-down, switch-mode converter  
with built-in power MOSFETs. It offers a very  
compact solution to achieve a 2A continuous  
output current with excellent load and line  
regulation over a wide input supply range. The  
MP1496 has synchronous mode operation for  
higher efficiency over the output-current–load  
range.  
Wide 4.5V to 16V Operating Input Range  
100m/40mLow-RDS(ON) Internal Power  
MOSFETs  
Proprietary Switching-Loss–Reduction  
Technique  
High-Efficiency Synchronous Mode  
Operation  
Fixed 500kHz Switching Frequency  
Can Synchronize with a 200kHz-to-2MHz  
External Clock  
Current-mode operation provides  
a
fast  
Externally Programmable Soft-Start  
OCP Protection and Hiccup  
Thermal Shutdown  
Output Adjustable Starting from 0.8V  
Available in an 8-pin TSOT-23 Package  
transient response and eases loop stabilization.  
Protective features include over-current  
protection and thermal shut down and external  
SS control.  
The MP1496 requires a minimal number of  
readily-available standard external components,  
and is available in a space-saving 8-pin  
TSOT23 package.  
APPLICATIONS  
Notebook Computers and I/O Power  
Digital Set-Top Boxes  
Flat-Panel Television and Monitors  
Distributed Power Systems
