Texas Instruments TPS62916EVM

Overview

TPS62916EVM from Texas Instruments is an evaluation module designed to characterize the TPS62916 6-A, low-noise synchronous buck converter operating from 3 V to 17 V input and delivering a fixed 1.2-V output. It implements dual-stage LC filtering, supports configurable switching frequency (1 MHz / 2.2 MHz), and enables precise ripple measurement via dedicated SMA connectors (J1, J2) with <10 µVRMS output ripple performance.

For engineers reviewing the TPS62916EVM datasheet, TPS62916EVM board layout, TPS62916EVM test setup, or TPS62916EVM loop response measurement, this module provides validated hardware for evaluating noise-sensitive power delivery in telecom, medical, and precision analog systems - including thermal performance at 6 A, configurable enable threshold, and feedforward capacitor integration.

Technical Context

The TPS62916EVM implements the full reference design for the TPS62916RPYR IC in a 2.5-mm × 3-mm QFN package, featuring dual LC filter stages (L1 + FB1 + C19–C23 and optional second stage), configurable S-CONF resistor (R4 = 6.04 kΩ for 1.4 MHz default), and NR/SS capacitor (C6 = 0.47 µF) for soft-start and low-frequency noise control.

It supports multiple configuration modes: JP2 selects between 1-MHz and 2.2-MHz fixed-frequency operation or enables S-CONF resistor programming; JP1 controls EN/SYNC functionality and allows external enable threshold setting via R6/R7; JP3 configures PG pin pullup voltage source.

FAQ

What is the primary purpose of the TPS62916EVM?

The TPS62916EVM is a Texas Instruments evaluation module built to fully characterize the TPS62916 6-A low-noise buck converter. It provides validated hardware for measuring output ripple (<10 µVRMS), thermal performance at full load, loop response, and configurable settings - enabling engineers to verify real-world behavior before integrating the TPS62916RPYR into noise-sensitive systems like data converters and clock supplies.

How does the TPS62916EVM support accurate output ripple measurement?

The TPS62916EVM supports accurate ripple measurement through two dedicated SMA connectors: J1 measures ripple before the second LC filter, and J2 measures ripple after it. TI specifies use of 50-Ω coax + DC blocker with full-bandwidth, DC-coupled oscilloscope settings - avoiding high-impedance probes that introduce noise and distortion. This methodology ensures valid sub-10-µVRMS readings consistent with the TPS62916 device specification.

Can the TPS62916EVM be used to evaluate different output voltages?

No - the TPS62916EVM is factory-configured for a fixed 1.2-V output using the internal feedback divider of the TPS62916RPYR. The board lacks provisions for external resistor-based VOUT adjustment. To evaluate other output voltages, users must refer to the TPS62916 datasheet and implement custom designs; the TPS62916EVM itself serves strictly as a 1.2-V reference evaluation platform.

What configuration options does the TPS62916EVM provide for the TPS62916 IC?

The TPS62916EVM offers multiple configuration options: JP2 selects 1-MHz or 2.2-MHz switching frequency (or enables R4-based programming); JP1 controls EN/SYNC and supports user-defined enable threshold via R6/R7; JP3 sets PG pin pullup voltage; C6 adjusts soft-start time and low-frequency noise filtering; and C8 adds feedforward capacitance to reduce low-frequency noise - all documented in the SLVUCO4 User's Guide.

Is the TPS62916EVM RoHS-compliant and FCC-certified?

The TPS62916EVM complies with RoHS directives per TI's standard manufacturing practices. As an evaluation module intended for R&D use only, it is not FCC-certified for end-product deployment. Per TI's Standard Terms, the board is labeled "FCC – Part 15 Compliant" for lab use but requires full system-level certification if integrated into a commercial product - no standalone FCC ID is assigned to the TPS62916EVM itself.
