EV2122-J-00A 6V, Dual 2A, Low Quiescent Current SYNC Buck Regulator
The EV2122-J-00A is used for demonstrating the performance of MPS’s MP2122, an internally compensated, 1MHz, fixed-frequency, dual-PWM, synchronous step-down regulator.
The MP2122 is ideal for powering portable equipment that runs from a single-cell, Lithium-Ion (Li+) battery due to 45µA low quiescent current. The output voltage can be regulated as low as 0.608V.
With peak current mode control and internal compensation, the MP2122 requires a minimal number of readily available, standard external components, and is available in an 8-pin, TSOT23 package.
