UCC28730QDRQ1 Description

Short technical summary and product information.

The UCC28730QDRQ1 from Texas Instruments is an AC/DC switching regulator with a Flyback topology, designed for automotive applications. It operates within a voltage range of 9V to 35V and features primary-side regulation, eliminating the need for an opto-coupler. This device offers ±5% voltage and current regulation across line and load variations.

 

Key features include automotive qualification, current limiting, DCM, green mode, high-voltage startup, input line monitoring, leading edge blanking, light load efficiency, low power operation, overcurrent protection, overtemperature protection, quasi-resonant operation, soft start, thermal shutdown, and valley switching. The controller has a maximum switching frequency of 83 kHz and enables zero-power standby consumption below 5 mW.

 

Packaged in a 7-SOIC surface mount package, the UCC28730QDRQ1 is suitable for designs requiring high efficiency and low standby power, such as automotive chargers. It also includes functional safety capabilities and documentation to aid in system design.
