UCC27200ADDAR

Overview

The UCC27200ADDAR is a high-frequency N-channel MOSFET gate driver from Texas Instruments, designed for half-bridge and full-bridge topologies. It integrates a high-side and low-side driver with independent inputs, offering a peak output current of 3A. The device supports a maximum bootstrap voltage of 120V and operates on a supply voltage range of 8V to 17V. Key electrical characteristics include an 8ns rise time and a 7ns fall time under a 1000pF load. It features built-in UVLO for both drivers and handles negative voltages on the high-side pin. The component is housed in an 8-pin SO PowerPAD package and is rated for operation between -40°C and +140°C.

Feature Summary

• Integrates a 120V bootstrap diode within the package to simplify external circuit design.
• Features enhanced ESD protection input structures for improved robustness in noisy environments.
• Provides independent control of high-side and low-side drivers with matched propagation delays.

Applications

• Half-bridge converters
• Full-bridge converters
• Two-switch forward converters
• Active clamp forward converters

Procurement Notes

Verify the specific suffix 'ADDAR' corresponds to the SO PowerPAD-8 package when sourcing. Confirm that the ordering part number matches the required tape-and-reel quantity specified by the manufacturer. Ensure compatibility with the target PCB footprint for the exposed thermal pad. Cross-reference the datasheet revision date to ensure all electrical specifications align with the design requirements.

Selection Notes

Select this component for applications requiring high switching frequencies above 1MHz and robust noise immunity. The integrated bootstrap diode reduces bill-of-materials count compared to discrete solutions. Consider the SO PowerPAD package for its superior thermal dissipation capabilities in power conversion circuits. Verify that the 120V bootstrap rating exceeds the maximum bus voltage of the intended application.

Part Context

This device belongs to the UCC27200A/1A series, which are enhanced versions of the widely used UCC27200/1 drivers. The series is optimized for telecom, datacom, and commercial power supplies. It offers improved performance over previous generations through better ESD handling and higher voltage tolerance on the high-side pin.

Replacement Considerations

UCC27200ADDA is a compatible variant in the same family with identical electrical specifications but may differ in packaging or reel configuration. Verify pinout and thermal pad dimensions before substitution.
