Texas Instruments TPS62000EVM-168

Overview

TPS62000EVM-168 from Texas Instruments is an evaluation module for the TPS62000 adjustable high-efficiency step-down DC-DC converter, configured to deliver 2.5 V output at up to 600 mA, operating from 2 V–5.5 V input, with enable, sync, and current-limit jumpers for mode control and test point access for VIN, VOUT, and PG signals.

For engineers reviewing the TPS62000EVM-168 datasheet, TPS62000EVM-168 pinout, TPS62000EVM-168 application, or TPS62000EVM-168 equivalent, this EVM supports rapid validation of low-power buck converter performance-including PFM/PWM mode switching, power-good monitoring, and external clock synchronization-in portable and battery-powered embedded systems.

Technical Context

The TPS62000EVM-168 implements the TPS62000DGS IC in a fully assembled, tested PCB layout optimized for low-noise, high-efficiency operation. It supports three configurable operating modes via on-board jumpers: enable (EN), synchronization (SYNC), and current limit (ILIM), enabling direct observation of PFM-to-PWM transition and load-dependent efficiency behavior.

Key circuit elements include a 10 µH Sumida CDRH5D28–100 inductor, dual 10 µF X5R ceramic output capacitors (C2/C5), 0.1 µF input bypass capacitor (C1), and precision feedback resistors (R1 = 825 kΩ, R2 = 182 kΩ) setting the nominal 2.5 V output. The open-drain Power Good (PG) signal is pulled up via R4 (470 kΩ) and asserts when VOUT exceeds 94.5% of nominal.

FAQ

What is the primary function of the TPS62000EVM-168?

The TPS62000EVM-168 is an evaluation module built around the TPS62000DGS adjustable buck converter IC. Its purpose is to enable rapid hardware validation of 2.5 V output regulation, efficiency profiling across load conditions, and functional testing of EN, PG, SYNC, and ILIM features-without requiring custom PCB design or component sourcing. TPS62000EVM-168 provides immediate access to critical test points and configurable jumpers for real-world power architecture prototyping.

Can the output voltage of the TPS62000EVM-168 be changed from 2.5 V?

Yes, the TPS62000EVM-168 is based on the adjustable TPS62000DGS IC and can be reconfigured for other output voltages between 0.8 V and VI by modifying the FB resistor divider network (R1/R2). The default 2.5 V setting uses R1 = 825 kΩ and R2 = 182 kΩ; alternate values are specified in the TPS62000 datasheet SLVS294. No soldering changes to the IC or inductor are required-only resistor replacement on the feedback path.

How does the SYNC jumper affect operation of the TPS62000EVM-168?

The SYNC jumper on the TPS62000EVM-168 selects between two core operating modes: placing it across pins 1–2 enables automatic PFM/PWM mode switching for peak efficiency across load ranges, while placing it across pins 2–3 forces fixed-frequency PWM mode to reduce output noise and simplify EMI filtering. An external 500 kHz–1 MHz CMOS clock may also be applied to the SYNC pin for system-level timing alignment-functionality directly exposed and testable on the TPS62000EVM-168 board.

What is the role of the Power Good (PG) signal on the TPS62000EVM-168?

The PG signal on the TPS62000EVM-168 is an open-drain output tied to the TPS62000DGS IC's PG pin and pulled up via R4 (470 kΩ). It asserts high when VOUT reaches ≥94.5% of nominal (2.3625 V at 2.5 V setpoint) and deasserts low when VOUT falls ≤92% (2.3 V), providing precise, real-time power sequencing feedback to host controllers. This signal is accessible via dedicated test point (VIN/VOUT/PG header) and is fully functional on the TPS62000EVM-168 without modification.

Is the TPS62000EVM-168 suitable for production use?

No-the TPS62000EVM-168 is explicitly designated by Texas Instruments for engineering development and evaluation only. As stated in the SLVU038B User's Guide, it lacks full commercial-grade safety, EMC compliance (e.g., CE/FCC), and manufacturing protections required for end-product deployment. TPS62000EVM-168 is intended solely for lab-based characterization, schematic validation, and firmware integration testing-not for inclusion in shipped products or certified systems.
