Texas Instruments TPS62134CEVM-595

Overview

TPS62134CEVM-595 from Texas Instruments is an evaluation module designed to validate the TPS62134C synchronous step-down converter for Intel Skylake VccEDRAM / VccEOPIO power rails. It supports 3–17 V input, delivers 0.8–1.05 V output at up to 3.2 A, and enables low-power mode via jumper JP4. The board includes test points, sense headers, and configurable VID/LPM control for real-world platform validation.

For engineers reviewing the TPS62134CEVM-595 datasheet, TPS62134CEVM-595 pinout, TPS62134CEVM-595 application, or TPS62134CEVM-595 equivalent, this EVM provides hardware-level access to input/output voltage sensing, soft-start timing verification (180 µs), thermal performance under load (e.g., VIN = 17 V, VOUT = 1.05 V, 3.2 A), and loop response measurement capability.

Technical Context

The TPS62134CEVM-595 implements the TPS62134C IC in a 3×3-mm QFN-16 package with dedicated jumpers for EN, VID0, VID1, LPM, and PG pull-up configuration. It integrates input (C1, C9) and output (C2, C5–C8) ceramic/tantalum capacitors, a 1-µH power inductor (XFL4020-102MEB), and test points for VIN, VOUT, SS, PG, and VOS signals.

Board-level features include dual voltage sense headers (J2/J5), isolated PG and SS signal access (J7/J8), external Vdd biasing (J9, 0.8–6 V), and PCB modifications enabling loop response analysis via R2 pad resistor insertion and VOS plane cut - all documented in TI's SLVUA82B user's guide.

FAQ

What is the primary purpose of the TPS62134CEVM-595?

The TPS62134CEVM-595 is an evaluation module built to validate the TPS62134C synchronous buck converter in Intel Skylake VccEDRAM / VccEOPIO power applications. It provides full hardware access to input/output voltage, current, soft-start, and low-power mode behavior - enabling engineers to verify electrical performance, thermal response, and system-level timing before integrating into final designs.

How does the TPS62134CEVM-595 support low-power mode evaluation?

The TPS62134CEVM-595 supports low-power mode evaluation via jumper JP4: placing the jumper across LOW and LPM enables low-power mode, while HIGH disables it. This allows direct correlation between LPM logic state and measured output voltage setpoint (0.8–1.05 V), efficiency curves, and quiescent current - all critical for Skylake platform power-state transitions.

Which voltage rails does the TPS62134CEVM-595 target per Intel Skylake specifications?

The TPS62134CEVM-595 targets the Intel Skylake VccEDRAM and VccEOPIO power rails. Its output voltage range (0.8–1.05 V at LPM = High) and input compatibility (3–17 V) are explicitly aligned with the electrical and sequencing requirements defined for those rails in the Skylake platform specification.

Can the TPS62134CEVM-595 be used to measure loop response?

Yes - the TPS62134CEVM-595 supports loop response measurement via two documented modifications: installing a 10-Ω resistor across R2 pads and cutting the VOS plane near C2 and L1. With these changes, a 10-mV ac signal can be injected to characterize gain/phase margins, as shown in Figure 3-2 of the SLVUA82B user's guide for the TPS62134CEVM-595.

What components on the TPS62134CEVM-595 are populated to support Intel Skylake VccEDRAM testing?

The TPS62134CEVM-595 includes the TPS62134CRGT IC (U1), 1-µH XFL4020-102MEB inductor (L1), 22-µF/47-µF ceramic output capacitors (C1/C2), 100-µF tantalum bulk capacitor (C10), and precision feedback resistors matching the 0.8–1.05 V output range. These components collectively ensure stable regulation, fast transient response, and thermal integrity required for VccEDRAM validation.
