The UC2823ADW from Texas Instruments is a high-speed Pulse Width Modulation (PWM) controller. It is an improved version of the UC3823/UC3825 PWMs, offering practical operation at switching frequencies up to 1 MHz. This controller is compatible with both voltage-mode and current-mode control methods.
Key electrical features include a 50-ns propagation delay to the output, high-current dual totem pole outputs capable of 2-A peak currents, and a low 100-μA startup current, making it suitable for off-line applications. It also incorporates a pulse-by-pulse current limiting comparator and a latched overcurrent comparator with full cycle restart for robust protection.
The UC2823ADW supports various topologies including Boost, Buck, Flyback, and Forward converters. It operates within a voltage range of 8.4V to 22V and has a maximum duty cycle of 100%. The operating temperature range is -40°C to 85°C.
This component is supplied in a 16-SOIC package and is designed for surface mount applications. Its control features include current limit, frequency control, ramp, and soft start.
