UCC28C58DR

DC DC Switching Controllers Overview

The UCC28C58DR is a low-power current-mode PWM controller from Texas Instruments, designed for industrial applications with a 30-V supply range. It supports Boost, Buck, Flyback, and SEPIC topologies in an SOIC-8 package. The device features a fixed switching frequency of 110 kHz and delivers up to 4 A output current. It operates within a temperature range of -40°C to +125°C, consumes 1.3 mA operating supply current at 28 V, and provides rail-to-rail outputs with isolated functionality.

DC DC Switching Controllers Feature Summary

• Supports multiple DC-DC converter topologies including Boost, Buck, Flyback, and SEPIC
• Provides high drive capability with up to 4 A output current
• Operates efficiently with low quiescent supply current consumption
• Features rail-to-rail output stages for robust signal integrity

DC DC Switching Controllers Applications

• Industrial power supply designs
• Buck converter implementations
• Boost converter architectures
• Flyback transformer-based power systems
• SEPIC topology applications

DC DC Switching Controllers Procurement Notes

Verify the specific suffix DR indicates the SOIC-8 surface-mount package configuration. Confirm that the component meets RoHS compliance requirements for your target market. Ensure the industrial temperature rating aligns with your operational environment constraints. Cross-reference the datasheet electrical characteristics against your system's voltage and current demands before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this controller when a single-channel solution supporting diverse topologies like Buck or Flyback is required. The 110 kHz frequency offers a balance between size and efficiency. Consider the 4 A drive strength for direct gate driving needs. The wide operating temperature range suits harsh industrial environments where standard commercial parts may fail.

DC DC Switching Controllers Part Context

This component belongs to the UCC28C58 series of low-power current-mode PWM controllers. It is manufactured by Texas Instruments under the PMIC category. The part is distinct from automotive variants like the UCC28C44QDRQ1, which carries AEC-Q100 qualification. It serves as a versatile control IC for various non-isolated and isolated power conversion schemes.

DC DC Switching Controllers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility if considering alternative manufacturers' devices. Check if equivalent switching frequencies and drive currents meet the specific application requirements without redesigning the feedback network.
