The NCP1012ST65T3G from ON Semiconductor is a self-supplied monolithic switcher designed for low standby-power offline Switched-Mode Power Supplies (SMPS). This integrated circuit combines a fixed-frequency current-mode controller with a 700V MOSFET, making it suitable for building rugged and low-cost power supplies.
Key features include a 65kHz operating frequency, a 67% duty cycle, and integrated fault protection for over load, over temperature, and over voltage conditions. The device also incorporates a 1.0 ms soft-start function and skip-cycle operation for excellent light-load efficiency without acoustic noise. It operates with an input voltage range of 8.5V to 10V and delivers up to 19W of power.
The NCP1012ST65T3G is available in a surface-mount SOT-223 (TO-261) package, offering a compact solution for space-constrained designs. Its design facilitates direct optocoupler connection and includes features like frequency jittering for improved EMI performance. The device is also Pb-Free and Halide-Free.
This offline switch is well-suited for applications such as low power AC/DC adapters for chargers and auxiliary power supplies for USB devices, appliances, and TVs.
