The onsemi NCP1028P100G is an offline switching controller designed for flyback topologies. This 7-pin PDIP package integrates a high-voltage MOSFET, enabling efficient power conversion up to 25W. Operating at a fixed switching frequency of 100kHz, it features internal startup circuitry with an 8.5V threshold and a wide operating voltage range of 7.2V to 10V for Vcc. Fault protection includes over power and short circuit capabilities. The device is suitable for applications requiring isolated outputs and operates within a junction temperature range of 0°C to 125°C. Its 80% duty cycle further contributes to its efficiency. This component is commonly utilized in consumer electronics and industrial power supplies.
