TopologyBuck Converter
Input voltage2.5-6 V
Output 11.2 V / 2 A
IC revision1.0

Description

The EV2161A-J-00A is used for demonstrating the performance of MPS’s MP2161A, a low voltage high switching frequency step-down switcher with built in power MOSFETs.MP2161A provides up to 2A highly efficient output with constant-on-time control for fast loop response.MP2161A is ideal for powering portable equipment that runs from a single cell Lithiumion (Li+) Battery. The output voltage can be regulated as low as 0.6V. High power efficiency over a wide load range is achieved by scaling down the switching frequency at light load to reduce the switchingrelated loss by constant on time control. Short circuit and thermal shutdown provides reliable, fault-tolerant operation. MP2161A is available in TSOT23-8 package.
