TPS5110PWG4

Overview

The TPS5110 is a synchronous step-down controller designed for high-performance power delivery in computing applications. It integrates two N-channel MOSFET drivers and supports input voltages from 3V to 14V. The device features adjustable output voltage via an external resistor divider, with a typical range of 0.8V to 3.6V. It operates with switching frequencies selectable between 200kHz and 700kHz using an external resistor. The controller includes comprehensive protection mechanisms such as over-current protection, thermal shutdown, and undervoltage lockout. It is housed in a 20-pin TSSOP package.

Feature Summary

• Integrated dual N-channel MOSFET drivers for synchronous buck conversion
• Adjustable switching frequency selection via external resistor
• Comprehensive protection including over-current, thermal, and undervoltage lockout

Applications

• Central processing unit (CPU) core voltage regulation
• Graphics processing unit (GPU) power supplies
• Server and workstation mainboard power distribution

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free RoHS compliance and halogen-free status as per Texas Instruments documentation. Confirm the package type matches the required PCB footprint. Ensure the ordering part number aligns with the exact pin configuration and electrical specifications listed in the official datasheet before procurement.

Selection Notes

Select this component when designing synchronous buck converters requiring integrated high-side and low-side drive capabilities. Consider the operating frequency range and input voltage window relative to the target application requirements. Evaluate the thermal performance and protection features against system reliability standards. Ensure compatibility with the control loop compensation network design.

Part Context

The TPS5110 belongs to Texas Instruments' family of synchronous step-down controllers optimized for multi-phase CPU and GPU power delivery. It complements other devices in the series by providing integrated driver stages, reducing external component count compared to non-integrated alternatives. This model is specifically engineered for high-current, high-efficiency applications in digital logic power systems.

Replacement Considerations

Check for direct pin-compatible replacements within the TPS51xx series or updated revisions from Texas Instruments. Verify that any substitute maintains identical driver current capabilities and protection thresholds. Ensure the alternative part supports the same switching frequency range and input voltage specifications.
