The UC1825J is a high-speed PWM controller designed for switched-mode power supply applications. It supports both voltage and current mode topologies and operates at switching frequencies up to 1 MHz. The device features a 50 ns propagation delay to output and high current dual totem pole outputs capable of sourcing and sinking 1.5A peak currents. Key protection features include pulse-by-pulse current limiting, under-voltage lockout with hysteresis, and a soft start function that also serves as a maximum duty cycle control. The controller is optimized for minimal propagation delays and maximized bandwidth, making it suitable for high-frequency applications. It operates with a low startup current of 1.1 mA and includes a wide bandwidth error amplifier. The UC1825J is available in a 16-pin CDIP package and is rated for operation over a temperature range of -55°C to 125°C. This product is ideal for engineers looking for a reliable and efficient PWM controller for their power supply designs.
