UC3823AN Description

Short technical summary and product information.

The Texas Instruments UC3823AN is a high-speed Pulse Width Modulation (PWM) controller. It is compatible with both voltage-mode and current-mode control methods and supports switching frequencies up to 1 MHz.

 

This controller features a 100% maximum duty cycle and operates within a voltage range of 8.4V to 22V. The operating temperature range is from 0°C to 70°C. Key electrical characteristics include a 50 ns propagation delay to the output and high-current dual totem pole outputs capable of 2A peak currents.

 

Functional enhancements include a latched overcurrent comparator with full cycle restart and a trimmed oscillator discharge current for accurate dead time control. The UC3823AN is suitable for applications requiring efficient power conversion.

 

The device is available in a 16-PDIP package and is designed for through-hole mounting.
