Texas Instruments TPS61288EVM-064

Overview

TPS61288EVM-064 from Texas Instruments is an evaluation module designed to demonstrate and validate the TPS61288 synchronous boost converter IC, which delivers up to 2.3 A output current at 13 V from a 3.5 V input, operating at 500 kHz with integrated 22 μH inductor and dual low-R_DS(on) FETs. It supports input voltage range of 2.7–8.8 V and enables rapid prototyping of high-efficiency DC-DC boost stages for portable power systems.

For engineers reviewing the TPS61288EVM-064 datasheet, TPS61288EVM-064 test setup, TPS61288EVM-064 board layout, or TPS61288EVM-064 schematic, this EVM provides verified performance data, accessible test points (VIN_S+, VO_S+, Bode±, SW), configurable jumpers (JP1 for VIN control, JP2 for EN), and full design documentation including 4-layer PCB layout files and BOM.

Technical Context

The TPS61288EVM-064 implements the TPS61288RQQR - a fully integrated 500 kHz synchronous boost converter in a 3.5 mm × 3.5 mm VQFN-HR11 package - with fixed 13 V output configured via 36.5 kΩ/14.3 kΩ FB divider. Input is applied across J1/J2 (VIN+/VIN−), output sourced from J3/J4 (VOUT+/VOUT−), and critical nodes are accessible via seven labeled test points for voltage, switching waveform, and stability analysis.

Board-level features include 2-oz copper on outer layers and 1-oz on inner layers, optimized thermal and EMI layout per TI's reference design, and user-modifiable components (e.g., R4, C14, C17) to adapt output voltage, compensation, or input/output capacitance per application requirements.

FAQ

What is the primary function of the TPS61288EVM-064?

The TPS61288EVM-064 is an evaluation module built around the TPS61288 synchronous boost converter IC. Its primary function is to provide a fully assembled, tested, and documented platform for evaluating the electrical performance, thermal behavior, and layout implementation of the TPS61288RQQR device - enabling engineers to validate 13 V output generation from low-input sources such as 3.5 V batteries before integrating into final systems. The TPS61288EVM-064 includes all necessary passives, test points, and configuration jumpers to support immediate bench testing.

Can the output voltage of the TPS61288EVM-064 be adjusted?

Yes, the output voltage of the TPS61288EVM-064 can be adjusted by modifying the feedback resistor divider network. The default 13 V output is set by R5 (36.5 kΩ) and R2 (14.3 kΩ); replacing either resistor changes the VOUT according to the TPS61288's FB pin equation. The board includes footprint space for optional R4 (2.2 Ω) and C14 (2200 pF) to support compensation tuning, and the JP1 jumper allows separation of control VIN from power VIN for independent biasing - all documented in the SLVUBW6A user's guide. This flexibility makes the TPS61288EVM-064 adaptable to varied system voltage requirements.

What test points are available on the TPS61288EVM-064 and how are they used?

The TPS61288EVM-064 provides seven labeled test points: TP1/TP2 for differential input voltage sensing, TP3/TP4 for differential output voltage sensing, TP5/TP6 for Bode plot stability analysis (loop gain/phase margin), and TP7 for direct observation of the switch node (SW) waveform. These points enable precise, low-noise measurements without soldering probes to IC pins or traces - critical for accurate efficiency, transient response, and stability characterization. All test point locations and functions are defined in Table 2-1 of the official user's guide for the TPS61288EVM-064.

Does the TPS61288EVM-064 include the TPS61288 IC in a specific package?

Yes, the TPS61288EVM-064 integrates the TPS61288RQQR - the 11-pin VQFN-HR (3.5 mm × 3.5 mm, 0.5 mm pitch) variant of the TPS61288 boost converter. This package features wettable flanks for automated optical inspection and is optimized for thermal performance in high-current applications. The U1 placement on the EVM matches TI's recommended layout for the VQFN-HR11 package, including thermal pad grounding and adjacent decoupling capacitor placement - ensuring the TPS61288EVM-064 accurately reflects production-ready implementation of the TPS61288RQQR.

How is enable/disable functionality implemented on the TPS61288EVM-064?

Enable/disable functionality on the TPS61288EVM-064 is controlled via JP2, a 3-position header jumper. By default, JP2 is installed in the VCC position, connecting the EN pin to internal VCC and enabling the TPS61288RQQR. To disable the converter, the jumper is moved to the GND position, pulling EN low. This hardware-based control eliminates reliance on external logic signals and allows safe, repeatable startup/shutdown during lab evaluation. The JP2 configuration is explicitly detailed in Section 2.2.1 of the TPS61288EVM-064 user's guide.
