UCC28084D Description

Short technical summary and product information.

The UCC28084D from Texas Instruments is a BiCMOS pulse width modulation (PWM) controller engineered for fixed-frequency, current-mode switching power supplies. This device is suitable for DC-to-DC applications and features dual output stages configured for a push-pull topology.

 

Key electrical specifications include an operating voltage range of 4.1V to 15V and a clock frequency of 200kHz. The controller supports a maximum duty cycle of 49% and offers features like current limiting and frequency control. It also provides a low start-up current of 120 µA and a typical run current of 1.5 mA.

 

The UCC3808x family, to which this part belongs, offers programmable slope compensation and an internal discharge transistor on the CS pin for improved dynamic response. The UCC28084D specifically has a soft-start interval time of 3.5 ms, making it suitable for applications requiring controlled power-up sequences.

 

Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount case, the UCC28084D is designed for efficient integration into various power supply designs. Its operating temperature range is -40°C to 85°C (TA).
