Rochester Electronics PMIC - AC DC Converters, Offline Switchers NCP1201P60

The NCP1201P60 is a PWM current-mode controller designed for universal offline power supplies, featuring low standby power consumption and robust fault protection mechanisms. It operates in a fixed frequency of either 60 kHz or 100 kHz and is housed in an 8-pin SOIC or PDIP package. This controller includes essential features such as brownout detection, latch-off mode for fault protection, and internal short-circuit protection, ensuring system reliability. The NCP1201P60 eliminates the need for an auxiliary winding by self-supplying from the high-voltage rail, simplifying design in applications like battery chargers and AC-DC adapters. It also supports skip-cycle operation for improved efficiency under light load conditions, minimizing acoustic noise. The device is RoHS compliant and free from lead and halogens, making it suitable for environmentally conscious designs. Typical applications include AC-DC adapters, offline battery chargers, and auxiliary power supplies for various consumer electronics.
