UCC3813DTR-5 Description

Short technical summary and product information.

The Texas Instruments UCC3813DTR-5 is an integrated circuit designed for off-line and DC-to-DC fixed-frequency current-mode switching power supplies. This low-power, BiCMOS controller operates at up to 1MHz and supports Boost, Flyback, and Forward converter topologies.

 

Key electrical specifications include an operating voltage range of 3.6V to 12V and a maximum duty cycle of 49%. It features frequency control for regulation and a transistor driver output. The device operates within a temperature range of 0°C to 70°C.

 

Packaged in an 8-SOIC (0.154", 3.90mm Width) surface mount configuration, the UCC3813DTR-5 is designed for applications requiring efficient power conversion with minimal external components. Its typical starting supply current is 100µA, and typical operating current is 500µA.

 

This controller family offers features such as internal soft start and leading-edge blanking of the current-sense signal, simplifying design and improving performance. The 1A totem-pole output provides fast response times.
