Product details
Overview
TPS630250EVM-668 from Texas Instruments is an evaluation module designed to validate the operation of the TPS630250 buck-boost converter IC. It implements a fixed 3.3-V output at up to 2 A from a 2.5-V to 5.5-V input, using a single inductor and TI's proprietary buck-boost topology. The board supports both PWM and PFM modes via jumper JP2 and enables/disables the converter via jumper JP1 - ideal for rapid prototyping of portable power rails.
For engineers reviewing the TPS630250EVM-668 datasheet, TPS630250EVM-668 setup, TPS630250EVM-668 schematic, or TPS630250EVM-668 BOM, this page provides verified hardware configuration details, test point access (J10/J11), input/output header definitions (J1–J6), and mode-select jumpers critical for lab validation and pre-compliance testing of low-voltage DC-DC conversion stages.
Technical Context
The TPS630250EVM-668 implements the TPS630250 VQFN-14 IC in a fully assembled, tested layout optimized for thermal performance and noise control. It uses a 1.0-μH shielded composite inductor (XAL4020-102MEB) and Murata X5R ceramic capacitors (10 μF, 47 μF, 100 μF) to support high-current transient response and stable regulation across input voltage variation.
Input and output sensing headers (J2, J5) enable 4-wire measurement to eliminate lead resistance error, while test points J10 and J11 provide direct access to internal switch nodes L1 and L2 for oscilloscope probing during efficiency or switching waveform analysis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.5 V to 5.5 V - supports single-cell Li-ion, Li-polymer, or dual-cell alkaline/NiMH battery inputs without external regulators. |
| Output Voltage | 3.3 V ±1% (3.267–3.33 V typ.) - factory-configured fixed output with external feedback divider; suitable for MCU, RF, and sensor rail requirements. |
| Max Output Current | 2 A continuous - validated under free-air ambient conditions at 25°C; requires proper PCB copper area and airflow for sustained load. |
| Operating Modes | PWM (forced constant frequency) and PFM (power-save) selectable via JP2 - enables trade-off between light-load efficiency and EMI control. |
| Enable Control | Hardware EN pin accessible via JP1 - allows system-level power sequencing or shutdown with 1-MΩ pull-up option to VIN. |
| Test Point Access | J10 (L1 switch node), J11 (L2 switch node) - facilitates direct probing of internal FET switching waveforms without soldering or signal injection. |

FAQ
What is the primary function of the TPS630250EVM-668?
The TPS630250EVM-668 is an evaluation module that demonstrates and validates the performance of the TPS630250 buck-boost converter IC. It delivers a regulated 3.3-V output at up to 2 A from a 2.5-V to 5.5-V input, enabling rapid lab testing of power architecture before final PCB design. The TPS630250EVM-668 includes all necessary passives, jumpers for mode selection, and test points for real-time waveform analysis.
Can the output voltage of the TPS630250EVM-668 be adjusted?
No - the TPS630250EVM-668 is factory-configured for a fixed 3.3-V output using external feedback resistors R1 (560 kΩ) and R2 (180 kΩ). While the underlying TPS630250 IC supports adjustable output via external resistor dividers, the TPS630250EVM-668 layout does not include provisions for changing those values on-board without component replacement.
How do I enable or disable the converter on the TPS630250EVM-668?
Use jumper JP1: place it across ON and EN to enable the TPS630250; place it across OFF and EN to disable. An optional 1-MΩ pull-up resistor can be added between VIN and EN for remote enable control. The TPS630250EVM-668 does not include active logic-level enable circuitry - EN is directly tied to the IC's enable pin per the TPS630250RMW datasheet.
What are the key test points on the TPS630250EVM-668 and their purposes?
The TPS630250EVM-668 provides J10 for probing the L1 switch node and J11 for the L2 switch node - both referenced to GND. These allow direct oscilloscope measurement of internal FET gate-drive timing, inductor current ripple, and switching node transitions without modifying the board. J2 and J5 offer 4-wire input/output voltage sensing to eliminate lead resistance errors during precision regulation tests.
Is the TPS630250EVM-668 FCC-certified for emissions testing?
No - the TPS630250EVM-668 is an evaluation module intended for R&D use only and is not FCC-certified. Per TI's standard terms, it must be operated in a shielded environment or under experimental license when used for radiated emissions characterization. The TPS630250EVM-668 documentation explicitly states it is not approved for commercial deployment or finished product integration without full system-level compliance validation.
