Quality Control: Learn More
The onsemi NCP1051P100G is an offline switching controller designed for flyback topologies. This component features an integrated 700V power MOSFET, enabling simplified power supply designs with fewer external components. Operating at a fixed switching frequency of 100kHz, it supports up to 40W output power with a maximum duty cycle of 77%. The device incorporates comprehensive fault protection mechanisms, including overcurrent limiting, open-loop detection, overload protection, and over-temperature shutdown. It requires a supply voltage of 7.5V to 10V and initiates operation at 8.5V. The NCP1051P100G is housed in a 7-lead PDIP package suitable for through-hole mounting. This high-performance controller finds application in various power conversion systems, including AC-DC adapters, consumer electronics power supplies, and industrial control equipment.
