Texas Instruments TPS63806EVM

Overview

TPS63806EVM from Texas Instruments is an evaluation module designed to validate the TPS63806 single-inductor buck-boost converter IC, configured for fixed 3.3 V output, supporting 1.3 V–5.5 V input and delivering up to 2 A output current in both buck and boost modes. It serves as a hardware reference for power architecture validation in portable and low-voltage embedded systems.

For engineers reviewing the TPS63806EVM datasheet, TPS63806EVM setup instructions, TPS63806EVM board layout, or TPS63806EVM schematic, this page provides verified operational context, interface definitions, supply range validation, jumper configuration guidance, and BOM-level component traceability for rapid prototyping and design-in support.

Technical Context

The TPS63806EVM implements the TPS63806YFF IC-a highly efficient, internally compensated buck-boost controller in a 15-pin, 2.3 mm × 1.4 mm BGA package-configured with R1 = 511 kΩ and R2 = 91.0 kΩ to set VOUT = 3.3 V. It supports automatic PFM/PWM mode transition via JP1 and enables/disables operation via JP2.

Input sensing (J1 pins 3–4) and output sensing (J2 pins 3–4) provide Kelvin connections for accurate voltage regulation feedback. The board integrates a 470 nH shielded inductor (XFL4015-471MEC), 150 µF bulk output capacitor (T530D157M010ATE005), and dual 47 µF ceramic output capacitors (GRM188R60J476ME15D) to stabilize transient response across load steps.

FAQ

What is the purpose of the TPS63806EVM?

The TPS63806EVM is a Texas Instruments evaluation module built around the TPS63806YFF buck-boost converter IC. Its primary purpose is to enable rapid functional validation, efficiency measurement, and dynamic load testing of the TPS63806 under real-world conditions-including input voltage ranges from 1.3 V to 5.5 V and output currents up to 2 A. Engineers use the TPS63806EVM to verify layout practices, confirm regulation accuracy, and evaluate mode transitions before committing to custom PCB designs.

How is the output voltage set on the TPS63806EVM?

The TPS63806EVM has a fixed 3.3 V output achieved using a precision resistor divider formed by R1 (511 kΩ) and R2 (91.0 kΩ) connected to the FB pin of the TPS63806YFF IC. This configuration follows the device's internal 0.5 V reference and adheres to the formula VOUT = 0.5 V × (1 + R1/R2). The board also supports adjustable outputs between 1.8 V and 5.0 V by replacing these resistors per the TPS63806 datasheet recommendations.

What are the key interface connectors on the TPS63806EVM?

The TPS63806EVM features three main interfaces: J1 (input) with VIN, input sense (S+/S−), and GND; J2 (output) with VOUT, output sense (S+/S−), and GND; and J3 (PG test point) for Power Good monitoring. All sense lines are Kelvin-connected to minimize PCB trace resistance errors. JP1 selects PFM or PWM mode, while JP2 controls enable/disable functionality-providing full hardware-level control without external logic.

Can the TPS63806EVM operate below 1.8 V input?

Yes-the TPS63806EVM supports start-up and operation down to 1.3 V input, as specified in its performance table. However, the guaranteed start-up voltage is 1.8 V; operation below that requires careful attention to input source impedance and capacitor ESR to ensure reliable startup under cold or high-impedance conditions. The TPS63806EVM's input stage is optimized for low-VIN battery applications, including partially discharged single-cell Li-ion or multi-cell alkaline sources.

Does the TPS63806EVM include thermal management provisions?

The TPS63806EVM uses the TPS63806YFF in a 2.3 mm × 1.4 mm BGA package with thermal pad exposed on the bottom side. The evaluation board includes thermal vias beneath U1 and copper pour on inner layers to enhance heat dissipation. While no heatsink is mounted, the layout supports ≤2 A continuous operation at 25°C ambient; derating is required above 60°C case temperature. Thermal performance data is documented in the SLVUBJ2 user's guide.
