The UC3825ADWTR from Texas Instruments is a high-speed Pulse Width Modulation (PWM) controller. It is designed for applications requiring voltage-mode or current-mode control methods, operating at switching frequencies up to 1 MHz.
Key electrical specifications include an operating voltage range of 8.4V to 22V and a maximum duty cycle of 50%. It features a propagation delay of 50 ns to the output and provides high-current dual totem pole outputs capable of 2-A peak currents. The controller includes features such as pulse-by-pulse current limiting and a latched overcurrent comparator with full cycle restart.
This device is available in a 16-SOIC package and is suitable for surface mount applications. The operating temperature range is 0°C to 70°C (Ambient). Its design incorporates features like soft start and frequency control, making it versatile for various power management designs.
The UC3825ADWTR is an improved version of standard PWM controllers, offering enhanced performance in circuit blocks like the error amplifier and overcurrent comparator. It is compatible with multiple topologies including Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull.
