Integrated DC-DC Converter - Power over Ethernet and Telecom NCP1030, NCP1031 The NCP1030 and NCP1031 are a family of miniature high−voltage monolithic switching regulators with on−chip Power Switch and Startup Circuits. The NCP103x family incorporates in a single IC all the active power, control logic and protection circuitry required to implement, with minimal external components, several switching regulator applications, such as a secondary side bias supply or a low power dc−dc converter. This controller family is ideally suited for 48 V telecom, 42 V automotive and 12 V input applications. The NCP103x can be configured in any single−ended topology such as forward or flyback.
