ON Semiconductor's NCP3231 and NCP3232 high current, high efficiency voltage-mode synchronous buck converters offer a wide input voltage range of 4.5 V to 18 V, and 4.5 V to 21 V respectively. Output voltages are generated as low as 0.6 V at up to a 25 A DC load. The devices integrate multiple protection features including a fault condition hiccup mode, thermal shutdown, as well as over and under voltage protection. This ensures support for applications such as cellular base stations, telecom and network equipment, and server and storage systems.
