UC2827DW-1 Description

Short technical summary and product information.

The UC2827DW-1 from Texas Instruments is a versatile PWM controller integrated for cascaded buck and push-pull converter applications. It supports multiple output and high voltage output converters, operating at frequencies up to 500 kHz.

 

This controller features a high voltage, high current floating driver for the buck converter stage. The UC3827-1 variant offers push-pull drivers with overlapping conduction periods, suitable for current-fed modes. The UC3827-2 variant provides non-overlapping conduction periods for voltage-fed modes. It supports average current mode, peak current mode, or voltage mode with input voltage feedforward control for the buck power stage.

 

Key electrical characteristics include a voltage range of 7.6V to 20V, a maximum duty cycle of 91%, and a frequency control feature. The device is housed in a 24-SOIC package and is designed for surface mount applications. The operating temperature range is -40°C to 85°C.

 

This part is not recommended for new designs. Consider alternate products for new projects.
