Beschreibung

The MCP19035 is a highly-featured, highly-integrated, Synchronous Buck Controller in a space-saving 10-pin DFN 3 x 3 mm package, that operates from input voltage sources up to 30V. Integrated features include high and low-side MOSFET drivers, fixed-frequency voltage mode control, internal oscillator and reference voltage generator, overcurrent protection on both the high- and low-side devices, Power Good circuit and overtemperature protection. A minimal number of external components are necessary to develop a complete, high-performance Synchronous Buck Converter power supply.

Eigenschaften
