UCC27222PWPG4

Gate Driver Overview

The UCC27222PWPG4 is a high-efficiency predictive synchronous buck gate driver manufactured by Texas Instruments. It features dual drivers with ±3 A peak output current capability and operates within a supply voltage range of 3.7 V to 20 V. The device utilizes a 14-pin HTSSOP PowerPAD package for thermal enhancement. Key electrical parameters include rise and fall times of 17 ns, an operating temperature range from -40°C to +105°C, and TTL logic input thresholds. It integrates a 6.5 V gate drive regulator and supports non-inverting and inverting configurations.

Gate Driver Feature Summary

• Predictive gate drive technology minimizes body-diode conduction and reverse recovery losses to maximize converter efficiency.
• Transparent synchronous buck operation allows direct control from single-ended PWM input signals without complex timing adjustments.
• On-board 6.5 V gate drive regulator provides stable power for high-side switching under varying bus conditions.

Gate Driver Applications

• Non-isolated single or multi-phased DC-to-DC converters
• Processor power delivery systems
• General computer and telecom datacom applications

Gate Driver Procurement Notes

Verify the specific suffix PG4 indicates lead-free compliance and RoHS status against the latest manufacturer datasheet. Confirm the 14-HTSSOP PowerPAD package dimensions match your PCB footprint requirements. Ensure the component meets the required moisture sensitivity level (MSL) handling procedures during assembly to prevent damage.

Gate Driver Selection Notes

Select this component when designing synchronous buck converters requiring predictive drive capabilities to reduce switching losses. The ±3 A output current is suitable for driving medium-power MOSFETs. Consider the 14-pin HTSSOP package for its thermal performance advantages over standard TSSOP packages in space-constrained designs.

Gate Driver Part Context

This part belongs to the UCC27222 series of high-efficiency predictive synchronous buck drivers. It is designed specifically for optimizing efficiency in DC-to-DC conversion applications by addressing reverse recovery issues inherent in synchronous rectification. The series includes variants like UCC27221 and UCC27222 with different pinouts or configurations.

Gate Driver Replacement Considerations

UCC27222PWPR is a compatible alternative within the same series offering identical functional specifications in a reel packaging format instead of tube.
