Product Description

Texas Instruments UC3825DW is a 16-pin SOIC package current mode PWM controller featuring two output channels with a maximum switching frequency of 1000 kHz and a maximum supply voltage of 125V. This device is engineered for high-frequency power management applications including flyback controllers, providing stable and efficient voltage and current regulation.

The controller operates with a supply current of just 4 mA, delivering 1.5 A output current per channel and permitting a maximum duty cycle of 85%, enabling precise power modulation. It functions effectively across an operating temperature range of 0°C to 70°C, making it suitable for reliable industrial use.

This PWM controller uses primary-side regulation (PSR) to eliminate the need for optocouplers, enhancing system efficiency and simplifying design. Its compact SOIC surface mount package measures 10.28 mm in length, 7.52 mm in width, and 2.35 mm in height, suitable for space-constrained circuit boards.

The UC3825DW is ideal for industrial, laboratory, and power management applications where consistent voltage and current control are critical. It supports flyback converters and voltage mode/current mode PWM control, optimizing transient response during large load changes.

16-pin SOIC surface mount package with compact dimensions. Two output channels supporting 1.5 A output current each. Maximum switching frequency of 1000 kHz for high-speed power supply control. Low supply current of 4 mA for energy efficient operation.

Maximum duty cycle of 85% to maintain stability under various loads. Operating temperature range from 0°C to 70°C for robust performance. Eliminates need for optocouplers via primary-side regulation. Supports flyback power supplies with improved transient response.
