MP2153 Synchronous Step-Down Converters Monolithic Power Systems (MPS) MP2153 Synchronous Step-Down Converters offer a 1.5A continuous output current with excellent load and line regulation over a 4V to 36V input supply range. The output voltage of the MP2153 can be regulated as low as 0.6V. A Constant On Time (COT) control scheme provides a fast transient response and eases loop stabilization. Using input voltage feed-forward, the MP2153 maintains a reasonably constant switching frequency across the input and output voltage ranges.
