TPS5300DAP

Overview

The TPS5300DAP is a triple-output DC/DC controller designed for mobile CPU power supplies. It integrates three synchronous step-down converters and one linear regulator within a single 32-pin HTSSOP package with an exposed pad. The device accepts an input voltage range of 3V to 28V, providing regulated outputs between 0.93V and 2V for the switching channels. This configuration supports high-density power delivery for complex processor architectures requiring multiple voltage rails simultaneously.

Feature Summary

• Integrates three synchronous buck controllers and one linear regulator in a compact footprint
• Designed specifically for multi-rail mobile CPU power supply applications
• Supports wide input voltage ranges suitable for battery-powered systems

Applications

• Mobile CPU power management
• Multi-voltage processor core regulation
• Battery-operated electronic devices requiring efficient power conversion

Procurement Notes

Verify component authenticity through authorized distributors or certified secondary market suppliers such as Rochester Electronics. Confirm that the specific suffix DAP corresponds to the tube packaging variant. Check for obsolescence status and ensure compatibility with existing board layouts before procurement.

Selection Notes

Select this component when designing power stages for processors requiring three distinct switched voltage rails alongside a linear regulator. Ensure the design accommodates the 32-pin HTSSOP thermal requirements. Verify that the input voltage profile remains within the 3V to 28V operational limits for stable performance.

Part Context

This part belongs to Texas Instruments' family of mobile CPU power controllers. It serves as a specialized solution for integrating multiple power phases into a single IC, reducing component count and PCB area compared to discrete solutions. The device addresses the power distribution challenges inherent in modern portable computing hardware.

Replacement Considerations

Public confirmed substitutes include the TPS5300DAPR and TPS5300DAPG4 variants. These alternatives offer identical functional specifications but may differ in packaging format or lead-free compliance status. Cross-reference pinouts and thermal characteristics before substitution.
