MP2491C Step-Down Converter
Monolithic Power Systems' MP2491C step-down converter with programmable current limit and output voltage scaling control
The MP2491C from Monolithic Power Systems is a fully integrated, high-voltage, step-down converter. The device can achieve 6 A of continuous output current with excellent load and line regulation over a wide input supply range. Constant-on-time (COT) control operation provides very fast transient response, easy loop design, and very tight output regulation. Full protection features include overcurrent protection (OCP), hiccup current limiting, output overvoltage protection (OVP), and thermal shutdown. The MP2491C requires a minimal number of readily available, external components, and is available in a QFN-13 (2.5 mm x 3 mm) package.
