MCP1612
Single 1A, 1.4 MHz Synchronous Buck Regulator
Features Description The MCP1612 is a 1A, 1.4 MHz, fully-integrated,
current mode-controlled, synchronous buck regulator.
The MCP1612 is packaged in the 8-pin MSOP and
space-saving, 3x3 DFN packages. The DFN package
also provides a lower thermal resistance package
option for high-power, high ambient temperature
applications. With an input operating range from 2.7V
to 5.5V, the MCP1612 is ideal for applications that are
powered by one single-cell Li-Ion, 2-to 3-cell NiMH,
NiCd or alkaline sources. Fixed Switching Frequency: 1.4 MHz
Input Operating Voltage Range: 2.7V to 5.5V
Integrated Buck and Synchronous Switches
Adjustable-Output Voltage Range: 0.8V to 5.0V
100% Duty Cycle Capable for Low Input Voltage
