Product Description
Texas Instruments UC2825N is a 16-pin PDIP dual-channel PWM controller designed to provide efficient current-mode control at a maximum switching frequency of 1000 kHz. It supports a maximum supply voltage of 125V and an output current capacity of 1.5A with an output voltage of 5.2V. The device operates over a wide temperature range from -40°C to 85°C, making it suitable for demanding industrial and commercial power management applications.
This PWM controller is crafted for isolated flyback power supply regulation, offering both constant-voltage and constant-current outputs to enhance transient response during large load changes. Its primary-side regulation (PSR) technology eliminates the requirement for optocouplers, simplifying PCB design and improving reliability.
The UC2825N features a maximum duty cycle of 80%, optimized for stable current-mode PWM control, and maintains a low supply current of 4 mA, promoting overall power efficiency. Packaged for through-hole mounting in a standard 16-pin PDIP format, it facilitates straightforward integration into legacy and new designs.
Industrial use cases include power supplies for manufacturing equipment, electronic control systems, and instrumentation requiring precise and reliable PWM control. Though it does not have automotive certification, its specifications suit a broad range of laboratory, commercial, and industrial power management tasks.
