The NCP12400CAHAB0DR2G from ON Semiconductor is a fixed-frequency current-mode controller designed for flyback converters. It operates at a frequency of 65 kHz and supports a voltage range of 8.9V to 28V. This device is housed in a 7-SOIC package and is designed for surface mounting.
Key features include timer-based overload protection with latched or autorecovery options, adjustable overpower protection dependent on mains voltage, and a high-voltage current source with brown-out detection and dynamic self-supply. It also incorporates frequency foldback for maximized performance in light load and standby conditions, and frequency modulation for a softened EMI signature. The controller includes internal thermal shutdown and provides fault input for overvoltage and over temperature protection.
Typical applications for this controller include offline adapters for notebooks, LCDs, and printers, as well as offline battery chargers and consumer electronic power supplies. Its design simplifies the VCC circuitry and allows for very low no-load standby power consumption.
