EV2172-J-00A 2A, 5.5V, 2.6MHz, Synchronous Step-Down Switcher Evaluation Board
The EV2172-J-00A is used for demonstrating the performance of MPS’s MP/MPQ2172, a low-voltage, high switching frequency, step-down switcher with built-in power MOSFETs. The MP/MPQ2172 provides up to 2A of highly efficient output with constant-on-time control for fast loop response. The MP/MPQ2172 is ideal for powering portable equipment that runs from a single cell Lithium-ion (Li+) battery. The output voltage can be regulated to 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 switching-related loss by constant-on-time control. Short circuit and thermal shutdown provides reliable, fault-tolerant operation. The MP/MPQ2172 is available in a TSOT23-8 package.
