Monolithic Power Systems (MPS) EV2122-J-00A Evaluation Board
Monolithic Power Systems (MPS) EV2122-J-00A Low Quiescent Current SYNC Buck Regulator demonstrates the performance of the MP2122 step-down regulator. The MP2122 is an internally compensated 1MHz fixed-frequency dual PWM synchronous step-down regulator ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) Battery due to 45uA low quiescent current.
The MPS EV2122-J-00A Evaluation Board regulates output voltage as low as 0.608V and offers peak current mode control and internal compensation.
The MP2122 requires a minimum of readily available standard external components and is housed in an 8-pin TSOT23 package.
