NCP1246BD065R2G Description

Short technical summary and product information.

The ON Semiconductor NCP1246BD065R2G is a fixed-frequency, current-mode controller specifically designed for flyback converter applications. It features a switching frequency of 65kHz and a maximum duty cycle of 80%, making it suitable for efficient power conversion.

 

This controller operates within an input supply voltage range of 8.9V to 28V and has a typical operating supply current of 1.85mA. It offers various fault protection mechanisms, including current limiting, overload, overpower, over-temperature, and over-voltage protection. The device is designed for isolated output configurations.

 

Packaged in an 8-SOIC (0.154", 3.90mm Width) case, the NCP1246BD065R2G is designed for surface mounting. It operates across a wide temperature range of -40°C to 150°C (TJ).

 

Key features include dynamic self-supply for simplified VCC circuitry, frequency foldback for light load efficiency, and timer-based overload protection. These characteristics make it a robust choice for AC-DC adapters, offline battery chargers, and consumer electronic power supplies.
