The UC3825N from Texas Instruments is a high-speed PWM (Pulse Width Modulation) controller IC optimized for high-frequency switched-mode power supply applications. It supports various topologies including Buck, Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull.
This controller operates with a supply voltage range of 8.4V to 30V and features a maximum duty cycle of 85%. It provides two outputs with a single phase and a transistor driver output type. Key electrical features include a practical operating switching frequency up to 1MHz, 50ns propagation delay to output, and high current dual totem pole outputs capable of 1.5A peak current. It also includes features like pulse-by-pulse current limiting, soft start, and under-voltage lockout with hysteresis.
The UC3825N is available in a 16-PDIP package and is designed for through-hole mounting. Its operating temperature range is from 0°C to 70°C. This controller is suitable for applications requiring efficient power conversion and precise control.
Note: This part is not recommended for new designs.
