Texas Instruments TPS629210-Q1EVM

Overview

TPS629210-Q1EVM from Texas Instruments is an evaluation module designed to characterize the TPS629210-Q1 automotive-grade 1-A synchronous buck converter in SOT583 package. It supports configurable MODE/S-CONF pin settings for forced PWM or auto PFM with TI AEE™ mode, 2.5-MHz switching, and external or internal feedback selection. The EVM enables efficiency, load/line regulation, loop response, and thermal performance testing under real operating conditions including 3–17-V input and 3.3-V output at up to 1-A load.

For engineers reviewing the TPS629210-Q1EVM datasheet, TPS629210-Q1EVM test setup, TPS629210-Q1EVM jumper configuration, or TPS629210-Q1EVM schematic and BOM, this page delivers verified board-level specifications, validated measurement procedures, and application-specific configuration guidance for automotive power supply validation.

Technical Context

The TPS629210-Q1EVM implements a complete test platform for the TPS629210-Q1 IC, featuring configurable input/output sense points (J1/J2), six user-modifiable jumpers (JP1–JP4, JP2 dual-row), and on-board net ties (NT1, NT2) for FB pin floating or loop injection. It supports both internal VSET (1.8 V or 3.3 V) and external resistor-divider feedback configurations.

Test capabilities include precise enable threshold programming (6.5-V rise / 5.85-V fall), selectable PG pull-up voltage (VIN or VOUT), feedforward capacitor option (C10), and loop bandwidth/phase margin measurement via 10-Ω injection resistor. All configurations align with the AEC-Q100 qualified TPS629210-Q1's automotive timing, safety, and reliability requirements.

FAQ

What is the primary function of the TPS629210-Q1EVM?

The TPS629210-Q1EVM is an evaluation module used to validate the electrical performance, thermal behavior, and configuration flexibility of the TPS629210-Q1 automotive synchronous buck converter. It provides accessible test points, configurable jumpers, and documented measurement methods to verify efficiency, transient response, loop stability, and enable threshold behavior under real-world automotive input conditions.

How do I configure the TPS629210-Q1EVM for internal feedback (VSET) operation?

To use internal feedback on the TPS629210-Q1EVM, cut net tie NT1 on the back side of the board to float the FB pin, then remove R1 and adjust R2 to set the desired output voltage (e.g., 34 kΩ yields 1.8 V). Ensure JP2 is removed to avoid conflict with external feedback - incorrect configuration risks device damage due to missing feedback control as explicitly warned in Section 3.3 of the User's Guide.

Can the TPS629210-Q1EVM measure loop bandwidth and phase margin?

Yes, the TPS629210-Q1EVM supports loop response measurement by cutting net tie NT2 and installing a 10-Ω 0603 resistor on the bottom layer, enabling AC signal injection (10-mV_pp) across the resistor. This method, detailed in Section 3.8 and shown in Figure 3-2, allows direct Bode plot acquisition for bandwidth (139 kHz) and phase margin (86°) validation per the TPS629210-Q1's internally compensated architecture.

What input voltage range is supported by the TPS629210-Q1EVM?

The TPS629210-Q1EVM supports an input voltage range of 3 V to 17 V, fully covering automotive battery operational extremes - including start-stop (6–16 V), cold-crank (down to 3 V), and load-dump (up to 17 V). Input is applied via J1 with dedicated sense pins (S+/S−) to eliminate lead resistance error during efficiency and regulation testing.

Does the TPS629210-Q1EVM include provisions for power good (PG) monitoring?

Yes, the TPS629210-Q1EVM includes JP3 for accessing the PGOOD signal (pin 1) with ground reference (pin 2), and JP4 to select PG pull-up voltage source - either VIN or VOUT via 100-kΩ resistor. If unused, JP3 should be shorted to GND; JP4 can be left unjumpered to connect to an external <18-V pull-up, enabling flexible system-level power sequencing verification.
