UC2825AQDWRQ1 Description

Short technical summary and product information.

The UC2825AQDWRQ1 from Texas Instruments is a pulse-width modulation (PWM) controller, serving as an improved version of the UC3825. This device is qualified for automotive applications and supports multiple topologies including Boost, Flyback, Forward Converter, Full-Bridge, Half-Bridge, and Push-Pull.

 

Key electrical characteristics include an operating voltage range of 8.4V to 22V and a maximum switching frequency of 1MHz. It features a maximum duty cycle of 85% and offers control features such as current limit, frequency control, ramp, and soft start. The controller provides a 2A peak output current and has a low startup current of 100 µA.

 

Designed for surface mount, the UC2825AQDWRQ1 comes in a 16-SOIC package with dimensions of 7.50mm width. Its operating temperature range is -40°C to 125°C (TJ). The device is compatible with voltage-mode or current-mode control methods and offers features like an error amplifier with a 12 MHz gain bandwidth product and a 2 mV input offset voltage.
