The NCP1246BLD100R2G from ON Semiconductor is a fixed-frequency, current-mode controller specifically designed for Flyback converters. This integrated circuit simplifies auxiliary supply design with its Dynamic Self-Supply feature, utilizing an internal startup current source.
Key electrical specifications include a nominal switching frequency of 100 kHz, an operating voltage range of 8.9V to 28V, and an 80% duty cycle. It offers robust fault protection, including current limiting, over load, over power, over temperature, and over voltage.
The device operates within a temperature range of -40°C to 125°C (TJ). It features a timer-based overload protection and supports frequency foldback for improved light-load efficiency. The controller also includes frequency modulation for a softened EMI signature and adjustable overpower protection.
Packaged in a 7-SOIC (8-SOIC, 0.154" Width, 7 Leads) surface-mount package, the NCP1246BLD100R2G is suitable for various AC-DC adapter applications, including those for notebooks, LCDs, and printers, as well as offline battery chargers and consumer electronic power supplies.
