The UC3842BD1R2G from On Semiconductor is a fixed-frequency, current-mode controller designed for efficient Off-Line and DC-DC converter applications. It offers a cost-effective solution with minimal external components, featuring a trimmed oscillator for precise duty cycle control and a temperature-compensated reference.
Key electrical specifications include an operating voltage range of 10V to 30V and a maximum duty cycle of 96%. The controller supports various topologies such as Boost and Flyback, with a maximum operating frequency of up to 500kHz. It includes essential control features like frequency control and a transistor driver output.
This device is housed in an 8-SOIC package, suitable for surface mounting. The operating temperature range is 0°C to 70°C (TA). Protective features include undervoltage lockouts and cycle-by-cycle current limiting, making it a robust choice for power supply designs.
The UC3842BD1R2G is Pb-Free and Halide-Free, aligning with environmental standards. Its design is optimized for applications requiring precise control over power conversion processes.
