DC DC Switching Controllers datasheet and documents for UCC2813DTR-3

UCC2813DTR-3

DC DC Switching Controllers Overview

The UCC2813DTR-3 is a low-power economy BiCMOS current mode PWM controller designed for offline and DC-to-DC fixed-frequency switching power supplies. It operates at a maximum frequency of 1 MHz with a 50% maximum duty cycle. The device features an internal full-cycle soft start, leading-edge blanking, and a 1 A output driver. It supports Boost, Flyback, and Forward topologies in an SOIC-8 package, with an operating temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

Integrates all control and drive elements for fixed-frequency current mode PWM applications
Includes internal full-cycle soft start and current detection input with leading-edge blanking
Compatible pin configuration with UC384x series for simplified design transitions

DC DC Switching Controllers Applications

Offline power supply designs
DC-to-DC converter circuits
Battery-powered systems requiring low power consumption

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'DTR-3' against the manufacturer's official datasheet to confirm the UVLO threshold and reference voltage levels. Ensure the ordering part number matches the required temperature grade and packaging format. Cross-reference with the UCC2813 family specifications to validate functional parameters before procurement.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring a cost-effective, low-power solution with minimal external component count. It is suitable for designs needing compatibility with UC384x footprints while offering enhanced features like integrated soft start. Consider the 1 MHz switching frequency and 50% duty limit when designing transformer and feedback loops.

DC DC Switching Controllers Part Context

This part belongs to the UCC2813-x series, which provides various options for package type, temperature range, maximum duty cycle, and critical voltage levels. The UCC2813 variant specifically targets the industrial temperature range (-40°C to 85°C), distinguishing it from the commercial grade UCC3813 series (0°C to 70°C).
