Categories: AC DC Converters, Offline Switches
Quality Control: Learn More
The onsemi NCP1051P100 is a high-performance, offline switching controller designed for flyback topologies. Operating at a fixed frequency of 100kHz, this component integrates a high-voltage MOSFET with a current-mode controller, simplifying power supply designs. It is engineered for applications requiring up to 40W output power with isolated output. Key features include internal startup circuitry, a wide operating voltage range of 7.5V to 10V for Vcc, and a breakdown voltage of 700V. Fault protection is comprehensive, encompassing current limiting, open loop, overload, and over-temperature protection. The NCP1051P100 is housed in a 7-lead PDIP package, suitable for through-hole mounting. Its robust design and integrated protection mechanisms make it well-suited for use in various industrial and consumer electronics power supplies.
