Quality Control: Learn More
The onsemi NCP1217P133 is a high-performance offline switching controller designed for flyback topologies. Operating at a fixed switching frequency of 133kHz, this component integrates a voltage mode PWM controller with a current mode capability, offering robust operation across a wide supply voltage range of 7.6V to 16V. With a startup voltage of 12.8V, it ensures reliable initiation of operation. The NCP1217P133 features internal protection mechanisms including overload, over-temperature, and short-circuit protection, contributing to system reliability. Its 74% maximum duty cycle and isolated output are critical for efficient power conversion. This component is commonly utilized in AC-DC converters for applications within the consumer electronics and industrial sectors. The device is supplied in a 7-PDIP package.
