DC DC Switching Controllers datasheet and documents for UCC3813DTR-5

UCC3813DTR-5

DC DC Switching Controllers Overview

The UCC3813DTR-5 is a low-power economy BiCMOS current mode PWM controller designed for offline and DC-DC fixed-frequency switching power supplies. It operates within an input voltage range of 8.2 V to 12 V, with a nominal input of 10 V. The device supports switching frequencies up to 1 MHz and delivers a maximum output current of 1 A. It functions in the commercial temperature range of 0°C to +70°C and utilizes an 8-pin SOIC package.

DC DC Switching Controllers Feature Summary

Integrates all control and drive components for switching power supplies with minimal external parts
Features internal full-cycle soft-start and fault soft-start capabilities
Includes internal leading-edge blanking for current sense inputs
Provides a 1 A totem-pole output driver

DC DC Switching Controllers Applications

Offline switch-mode power supplies
DC-DC converters
Battery-powered systems requiring lower reference voltages

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'DTR-5' against official Texas Instruments documentation to confirm the exact electrical characteristics, particularly the reference voltage level associated with the '-5' variant. Ensure the order matches the required commercial temperature range and SOIC-8 package configuration. Cross-reference datasheet revisions to validate pinout compatibility with existing designs.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring high-frequency operation up to 1 MHz with low quiescent current. The '-5' suffix indicates a specific reference voltage setting suitable for battery-powered systems compared to other variants in the series. Confirm that the 8.2 V minimum operating voltage aligns with the system's supply constraints and that the SOIC-8 package fits the PCB layout requirements.

DC DC Switching Controllers Part Context

This part belongs to the UCC3813-x series of low-power economy BiCMOS current mode PWM controllers. It shares pin configurations with the UC384x series but adds internal soft-start and leading-edge blanking features. The series offers various temperature ranges and reference voltage options to suit different power supply topologies.
