UCC27200DRMR

Overview

The UCC27200DRMR is a high-frequency N-channel MOSFET gate driver from Texas Instruments, designed for half-bridge and full-bridge converter applications. It features two independent drivers with a peak output current of 3 A for both sourcing and sinking. The device supports a maximum bootstrap voltage of 120 V and operates on a supply voltage range of 8 V to 17 V. Key performance metrics include an 8 ns rise time and a 7 ns fall time under a 1000 pF load. Propagation delay is specified at 20 ns, with turn-on and turn-off delays matched to within 1 ns. The component functions reliably across a junction temperature range of -40°C to +140°C.

Feature Summary

• Features enhanced ESD input structures and an isolated bus architecture to improve performance in noisy power environments.
• Integrates an on-chip 0.65 V forward voltage drop boot diode with 0.6 Ω resistance for simplified high-side drive requirements.
• Provides independent control for high-side and low-side drivers with matched switching delays to minimize cross-conduction.

Applications

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

Procurement Notes

Verify the specific suffix DRMR corresponds to the 8-VSON (4x4) package configuration when ordering. Confirm that the selected variant meets the required thermal dissipation specifications for the intended application environment. Ensure compatibility with the target PCB footprint and soldering profile for surface-mount assembly. Cross-reference the manufacturer's latest datasheet to confirm active status and any potential design changes.

Selection Notes

Select this component for applications requiring fast switching speeds and high noise immunity in power conversion circuits. The integrated boot diode reduces external component count compared to standard drivers. Consider the 8-VSON package for space-constrained designs while ensuring adequate thermal management capabilities are implemented on the PCB layout.
