Quality Control: Learn More
The onsemi NCP1203P40 is a SMARTMOS™ series offline switching controller designed for flyback topologies. This component operates at a fixed switching frequency of 40kHz and features an internal startup circuit with a voltage threshold of 12.8V. It requires a supply voltage (Vcc/Vdd) between 7.8V and 16V. The NCP1203P40 incorporates comprehensive fault protection mechanisms, including overload, over-temperature, and short-circuit protection. With an 80% duty cycle capability, it is suitable for isolated output applications. The device is packaged in an 8-PDIP (0.300", 7.62mm) through-hole mounting configuration and is rated for operation across an ambient temperature range of -40°C to 125°C. This component is widely utilized in power supply applications within the consumer electronics and industrial automation sectors.
