Monolithic Power Systems (MPS) MP1476 Step-Down Converters
Monolithic Power Systems (MPS) MP1476 Step-Down Converters are designed to achieve 2A continuous output current with excellent load and line regulation. These Monolithic Power Systems MP1476 converters feature high-efficiency synchronous mode operation, fast load transient response, Power-Save Mode (PSM) at light load, and internal Soft Start (SS). The MP1476 step-down converters attain higher efficiency over the output current-load range by executing high-efficiency synchronous mode operation. The Constant-on-Time (COT) control operation provides an easy loop design, fast transient response, and tight output regulation.
The MP1476 step-down converters consists of full protection features including Over-Current Protection (OCP), Short-Circuit Protection (SCP), thermal shutdown, and Under-Voltage Protection (UVP). Typical applications include security cameras, digital set-top boxes, flat-panel televisions, and monitors.
