●Low Power PWM Controller with On−Chip Power Switch and Startup Circuits for 48V Telecom Systems

●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. The NCP1030 is targeted for applications requiring up to 3 W, and the NCP1031 is targeted for applications requiring up to 6 W.
