The UC2825DW from Texas Instruments is a high-speed Pulse Width Modulation (PWM) controller optimized for high-frequency switched-mode power supply applications. It supports both voltage and current mode topologies, offering flexibility in design. This controller operates with a supply voltage range of 8.4V to 30V and features a maximum duty cycle of 80%.
Key electrical characteristics include a practical operation switching frequency up to 1MHz, a 50ns propagation delay to the output, and high current dual totem pole outputs capable of 1.5A peak current. It includes features such as pulse-by-pulse current limiting, soft start, and under-voltage lockout with hysteresis. The device is available in a 16-SOIC package, suitable for surface mount applications.
This controller is designed for applications requiring efficient power conversion, such as step-up, step-up/step-down, boost, flyback, forward converter, full-bridge, half-bridge, and push-pull topologies. Its wide bandwidth error amplifier and fully latched logic contribute to stable and jitter-free operation.
