Texas Instruments TPS63901EVM-100

Overview

TPS63901EVM-100 from Texas Instruments is an evaluation module designed to accelerate development and validation of the TPS63901 ultra-low-quiescent-current (75 nA typical) synchronous buck-boost converter. It supports input voltages from 1.8 V to 5.5 V, delivers up to 330 mA output current at 3.3 V, and enables configurable output voltages from 1.8 V to 5.0 V via jumper-selectable R2D interface. The EVM is used for power architecture prototyping in battery-powered IoT sensors and wearable medical devices.

For engineers reviewing the TPS63901EVM-100 datasheet, TPS63901EVM-100 setup procedure, TPS63901EVM-100 schematic, or TPS63901EVM-100 BOM, this page provides verified hardware configuration guidance, performance test data at 25°C, jumper-based voltage/current limit selection logic, and component-level layout documentation - all directly extracted from TI's official SLVUCC1 User's Guide.

Technical Context

The TPS63901EVM-100 implements the TPS63901 IC in a fully assembled, tested PCB form factor with accessible test points, dual-input/output connectors (J1/J2), and six SPST DIP switches (S1–S6) for resistor-divider configuration. It uses a 2.2 µH shielded inductor (L1), 150 µF tantalum polymer input capacitor (C1), and multiple 10–47 µF ceramic output capacitors to support stable operation across the full 1.8–5.5 V input range.

Configuration is managed through three dedicated pins (CFG1/CFG2/CFG3) routed to jumpers JP3–JP5 and switch banks S1–S6, enabling precise output voltage selection (VO1 or VO2 mode) and input current limiting (1 mA to unlimited) per Tables 2-1 and 2-2. The board includes sense lines (S+/S−) for accurate VIN/VOUT measurement and a 3-pin enable header (JP2) supporting external control or manual ON/OFF operation.

FAQ

What is the primary function of the TPS63901EVM-100?

The TPS63901EVM-100 is a ready-to-use evaluation module that demonstrates and validates the operation of the TPS63901 synchronous buck-boost converter. It allows engineers to rapidly test input/output behavior, configure output voltage and current limits via physical switches, and verify performance across the full 1.8–5.5 V input range without designing custom hardware. The TPS63901EVM-100 itself contains no active IC functionality beyond hosting the TPS63901 device.

How do I set the output voltage on the TPS63901EVM-100?

Output voltage on the TPS63901EVM-100 is set using the R2D interface: short JP1 between SEL and VO1 or VO2 to select mode, then configure S1–S6 switches per Tables 2-1 (VO2) or 2-2 (VO1) in the SLVUCC1 User's Guide. For example, to set VO2 = 3.3 V with unlimited current limit, turn ON S4.8 and S2.1. All CFG pins must have exactly one switch closed - floating CFG pins will cause undefined operation of the TPS63901EVM-100.

Does the TPS63901EVM-100 support external enable control?

Yes. The TPS63901EVM-100 provides access to the EN pin of the TPS63901 IC via JP2: the center pin is EN, and shorting it to ON activates the converter, while shorting to OFF disables it. To use external logic-level control, connect your signal to the center EN pin and leave both outer pins unshunted - the TPS63901EVM-100 accepts 1.2 V to 5.5 V enable signals compatible with standard CMOS outputs.

What input and output connectors does the TPS63901EVM-100 use?

The TPS63901EVM-100 uses two 6-pin 0.1-inch pitch headers: J1 for input (pins 1–2 = VIN, 3–4 = S+/S− sense, 5–6 = GND) and J2 for output (pins 1–2 = VOUT, 3–4 = S+/S− sense, 5–6 = GND). These allow direct connection to bench supplies and electronic loads using standard jumper wires or banana-to-pin adapters - no soldering required for basic functional testing of the TPS63901EVM-100.

Can the TPS63901EVM-100 be used to evaluate load transient response?

Yes. The TPS63901EVM-100 includes dedicated sense lines (S+/S−) at both input and output, enabling accurate real-time voltage monitoring during dynamic load steps. With its 150 µF input capacitor (C1) and parallel 22–47 µF output capacitors (C2–C9), the board maintains stability during fast transients typical of microcontroller wake-up events. Engineers routinely use the TPS63901EVM-100 to capture load step waveforms and validate loop response before committing to custom PCB designs.
