1.2A Peak, 6V, 3.5MHz, COT Synchronous Step Dwon Switcher

Overview

TopologyBuck Converter
Input voltage2.5-6 V
Output 11.2 V / 1 A
IC revision1.01

Description

The MP2160 is a monolithic step-down switch mode converter with built-in internal power MOSFETs. It achieves 1.2A peak continuous output current from a 2.7V to 6V input voltage with excellent load and line regulation. Theoutput voltage can be regulated as low as 0.6V.

The Constant-On-Time control scheme provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown.

The MP2160 is available in the small QFN8 1.5x2.0mm package and requires a minimum number of readily available standard external components.

The MP2160 is ideal for a wide range of applications including High Performance DSPs, FPGAs, PDAs, portable instruments and DVD drivers.
