The UCC28220DR from Texas Instruments is a BiCMOS interleaved dual-channel PWM controller designed for power management applications. It utilizes peak current mode control to ensure accurate current sharing between its two channels.
Key electrical specifications include an operating voltage range of 8.4V to 14.5V and an adjustable switching frequency from 200kHz up to 2MHz. The maximum duty cycle is programmable, with a clamp set between 60% and 90% per channel, and the device features a maximum duty cycle of 75% as specified in the product data. It supports both Flyback and Forward converter topologies.
This controller offers several features for enhanced performance, including cycle-by-cycle current limiting, programmable slope compensation, soft start, and accurate line undervoltage and overvoltage sensing with programmable hysteresis. It also includes a current sense discharge transistor for improved noise immunity and an opto-coupler interface.
The UCC28220DR is supplied in a 16-SOIC package suitable for surface mounting. Its operating temperature range is -40°C to 105°C (TA). The device operates from a 12V supply, featuring an 8.4V UVLO turn-on threshold.
