Monolithic Power Systems (MPS) MP2161 Synchronous Step Down Switchers
Monolithic Power Systems (MPS) MP2161 Synchronous Step Down Switchers are monolithic switch-mode converters with built-in internal power MOSFETs in a TSOT23-8 package. The MP2161 features 2A continuous output current from a 2.5V to 6V input voltage with excellent load and line regulation. The MP2161 allows a regulated output voltage as low as 0.6V.
The MPS MP2161 Synchronous Step Down Switchers offer a Constant-On-Time control scheme achieving a fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown.
The MP2161 is housed in the small TSOT23-8 package and requires a minimum number of readily available standard external components. The MP2161 is suitable for many applications, including high-performance DSPs, FPGAs, PDAs, and portable instruments.
