Texas Instruments High-Performance Analog DC DC Switching Controllers UC2823ADWTR

The UC2823ADWTR is a high-speed PWM controller designed for DC-DC switching applications. It operates with improved performance over its predecessors, featuring compatibility with both voltage-mode and current-mode control methods. The device supports practical switching frequencies up to 1 MHz and has a low startup current of 100 OºA, making it suitable for off-line applications. Key specifications include a 50-ns propagation delay to output and high-current dual totem pole outputs capable of 2-A peak currents. The error amplifier has a gain bandwidth product of 12 MHz and an input offset voltage of 2 mV, ensuring precise control. The current limit threshold is tightly controlled with a tolerance of 5%, and the oscillator discharge current is specified at 10 mA for accurate dead time control. The UC2823ADWTR also features a latched overcurrent comparator with full cycle restart capability, enhancing fault management. It is available in a 16-pin SOIC package and operates within a temperature range of -40¬8C to 85¬8C. This product is suitable for engineers looking for a reliable and efficient PWM controller for their power management needs.
