UC3825AN Description

Short technical summary and product information.

The UC3825AN from Texas Instruments is a high-speed PWM controller suitable for multiple topologies such as Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull configurations. It operates with an input voltage range of 8.4V to 22V and supports a maximum duty cycle of 50% with an adjustable frequency from 400kHz to 1MHz.

 

Key electrical features include a 50 ns propagation delay to the output, high-current dual totem pole outputs capable of 2A peak currents, and a low 100 μA startup current. The controller integrates features like pulse-by-pulse current limiting, a latched overcurrent comparator with full cycle restart, and soft start functionality. The operating temperature range is from 0°C to 70°C.

 

This device is available in a 16-PDIP package and is designed for through-hole mounting. Its versatile control features make it suitable for a wide array of power supply designs requiring precise regulation and protection mechanisms.
