Texas Instruments TPS63070EVM-693

Overview

TPS63070EVM-693 from Texas Instruments is an evaluation module designed to accelerate development and validation of the TPS63070 adjustable-output buck-boost converter IC. It supports input voltages from 2.0 V to 16 V, delivers up to 2 A output current in both buck and boost modes, and provides user-selectable 3.3 V or 5.0 V output via JP2 jumper configuration.

For engineers reviewing the TPS63070EVM-693 datasheet, TPS63070EVM-693 setup, TPS63070EVM-693 application, or TPS63070EVM-693 alternative evaluation platforms, this module enables rapid functional verification, efficiency measurement, thermal profiling, and layout reference analysis for high-efficiency single-inductor buck-boost power designs.

Technical Context

The TPS63070EVM-693 implements the TPS63070RNM IC - a single-inductor, internally compensated buck-boost converter in a 2.5-mm × 3-mm HotRod QFN-15 package. It operates across a 2400-kHz fixed switching frequency and supports seamless mode transition between buck and boost based on input-to-output voltage ratio.

Board-level features include dual-voltage selection (3.3 V/5.0 V), enable control (JP1), power-save/PWM mode selection (JP3), input/output sense lines (J1/J2 pins 3–4), and Power Good monitoring (J5). The EVM uses discrete external components including 1.5-µH shielded inductor L1, 68-µF tantalum output capacitor C10, and precision feedback resistors R1–R3 for adjustable output configuration.

FAQ

What is the primary function of the TPS63070EVM-693?

The TPS63070EVM-693 is an evaluation module built around the TPS63070 adjustable-output buck-boost converter IC. Its primary function is to provide a ready-to-use hardware platform for evaluating efficiency, transient response, thermal behavior, and layout practices of the TPS63070 in real-world power supply designs. Engineers use the TPS63070EVM-693 to validate system-level integration before committing to custom PCB development.

Can the TPS63070EVM-693 be used with fixed-output versions of the TPS63070?

Yes - the TPS63070EVM-693 PCB is designed to accommodate both adjustable and fixed-output variants of the TPS63070 IC. To use a fixed-output version, replace resistors R1 and R3 with 0-Ω jumpers and leave R2 position open, as documented in Section 1.3.2 of the user's guide. This hardware modification allows evaluation of fixed-output parts like TPS630701 without redesigning the board.

How do I configure the TPS63070EVM-693 for 3.3 V versus 5.0 V output?

Use jumper JP2: short the center pin to LOW for 3.3 V output, or short the center pin to HIGH for 5.0 V output. This selection directly controls the VSEL pin of the onboard TPS63070RNM IC. The default configuration shipped by TI is typically set to 5.0 V, but both options are fully supported and validated per the SLVUAO5A user's guide.

Does the TPS63070EVM-693 support power-save mode?

Yes - the TPS63070EVM-693 supports automatic power-save mode at light loads via jumper JP3. Short the center pin of JP3 to HIGH to enable automatic transition from PWM to power-save mode; short to LOW to force continuous PWM operation. This feature allows accurate efficiency measurement across load ranges and reflects real-world behavior of the TPS63070 in battery-sensitive applications.

What input and output connectors does the TPS63070EVM-693 use?

The TPS63070EVM-693 uses two 6-pin headers: J1 for input (VIN, input sense S+/S−, and GND) and J2 for output (VOUT, output sense S+/S−, and GND). These headers provide Kelvin-sense capability for precise voltage regulation validation and minimize measurement error due to PCB trace resistance. No proprietary or custom connectors are required - standard 0.1-inch pitch jumper wires or test leads suffice.
