MP2491C Step-Down Converter has programmable current limit

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.
