UC28023DW

DC DC Switching Controllers Overview

The UC28023DW is a high-speed PWM controller manufactured by Texas Instruments, designed for economy and efficiency in power conversion applications. It supports multiple topologies including Boost, Flyback, Forward, Full Bridge, Half Bridge, and Push-Pull configurations. The device features a single output with a maximum duty cycle of 100% and operates at a switching frequency of 1 MHz. It provides an output voltage of 5.1 V and can source up to 1.5 A. The component functions within a temperature range of -40°C to +105°C and is housed in a 16-pin SOIC package.

DC DC Switching Controllers Feature Summary

• Supports versatile multi-topology implementations including push-pull, half-bridge, full-bridge, forward, flyback, and boost circuits.
• Enables high-frequency operation with a 1 MHz switching capability for compact magnetic component design.
• Provides robust gate drive performance with 1.5 A output current capability and fast transition times.

DC DC Switching Controllers Applications

• High-density DC-DC converter designs requiring flexible topology selection
• Industrial power supplies utilizing flyback or forward architectures
• Bridge converter systems for isolated power delivery

DC DC Switching Controllers Procurement Notes

Verify the specific suffix (e.g., DW vs DWR) to confirm packaging type, as tube and reel variants exist. Ensure the order matches the required operating temperature range and pinout compatibility. Confirm RoHS compliance status through official documentation before integration into regulated assemblies.

DC DC Switching Controllers Selection Notes

Select this controller when a single-channel driver is needed for complex topologies like bridge or push-pull circuits. Consider the 1.5 A drive strength for direct MOSFET/IGBT control without external buffers. Evaluate the 1 MHz frequency limit against core loss requirements for the intended transformer design.

DC DC Switching Controllers Part Context

Part of the UC28023 series from Texas Instruments, focusing on high-speed PWM control. It shares family characteristics with other UC-series controllers but distinguishes itself through support for six distinct power topologies and a 100% duty cycle capability, suitable for demanding industrial and commercial power stages.

DC DC Switching Controllers Replacement Considerations

Check UC28023DWR for identical electrical specifications with tape-and-reel packaging. Verify UC28023DWRG4 for lead-free compliant versions if environmental regulations require it. Cross-reference UC28025DW only if dual-output functionality is acceptable despite different duty cycle limits.
