TPS51222RTVR

Overview

The TPS51222RTVR is a fixed-frequency notebook system power controller manufactured by Texas Instruments. It features a buck topology with two independent outputs capable of delivering up to 20 A each. The switching frequency is adjustable from 200 kHz to 1 MHz, and the output voltage range spans from 1 V to 12 V. The device operates within a temperature range of -40°C to +85°C and is housed in a 32-pin WQFN package.

Feature Summary

• Dual synchronous buck controllers designed for high-current notebook applications
• Adjustable switching frequency allows optimization for efficiency and component size
• Integrated protection mechanisms ensure reliable operation under varying load conditions

Applications

• Notebook system power management
• Point-of-load voltage regulation
• Multi-rail power distribution systems

Procurement Notes

Verify the RTVR suffix indicates tape-and-reel packaging when ordering. Confirm the specific revision level matches design requirements. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Cross-reference pinouts with official datasheets before PCB layout finalization.

Selection Notes

Select this component for designs requiring dual high-current rails with flexible frequency tuning. Evaluate thermal performance based on the 32-WQFN package constraints. Compare against single-output alternatives if current demands exceed individual channel limits. Consider input voltage ranges compatible with system battery or adapter specifications.

Part Context

This part belongs to the TPS51222 family of power controllers optimized for mobile computing platforms. It complements other TI PMIC solutions by providing dedicated high-current buck stages. The series supports various form factors through configurable feedback networks and timing resistors.

Replacement Considerations

Check for TPS51222 variants with different packaging options such as RTVT. Verify functional compatibility with existing control loops before substitution.
