MP2128  
2.5V-6V Input, 3MHz, 1A  
Synchronous Step-Down Converter  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2128 is a 3MHz constant frequency,  
current mode, PWM step-down converter with  
integrated main switch and synchronous  
rectifier that is ideal for powering portable  
equipment that runs from a single Li-Ion or Li-  
Polymer battery.  
High Efficiency: Up to 95%  
3MHz Constant Switching Frequency  
1A Available Load Current  
2.5V to 6V Input Voltage Range  
Output Voltage as Low as 0.6V  
Current Mode Control  
Cycle-by-Cycle Over Current Protection  
Short Circuit Protection  
Thermal Shutdown  
<1µA Shutdown Current  
Internal Soft-Start  
Space Saving 5-Pin SOT23 Package and  
8-pin, QFN8 2mm×2mm package  
The MP2128 can supply up to 1A load current  
from a 2.5V to 6V input voltage. The output  
voltage can be as low as 0.6V.  
Additional features include <1µA shutdown  
current, internal soft-start, cycle-by-cycle over  
current protection, short circuit protection, and  
thermal shutdown.  
The MP2128 is available in low profile (1.5mm)  
5-pin SOT23 and 8-pin, QFN8 2mm×2mm  
packages.
