The NCP1234AD100R2G from ON Semiconductor is a fixed-frequency current-mode controller specifically designed for flyback converter applications. This device operates at a frequency of 100kHz and supports an input voltage range from 9.5V to 28V, with a maximum duty cycle of 80%.
Key features include Dynamic Self-Supply (DSS) for simplified auxiliary supply design, frequency foldback and skip mode for improved light-load efficiency, and timer-based overload protection. It also offers adjustable overpower compensation and a latch-off input for severe fault conditions, such as overtemperature protection.
The controller is housed in a 7-SOIC package and is designed for surface mount applications. Its operating temperature range is -40°C to 150°C (TJ). The device is pin-to-pin compatible with previous NCP12xx families, facilitating design upgrades.
This component is suitable for various applications including AC-DC adapters for notebooks, LCDs, and printers, offline battery chargers, and consumer electronic power supplies. It is Pb-free, Halogen Free/BFR Free, and RoHS compliant.
