Product details
Overview
TPS562246EVM from Texas Instruments is a fully assembled and tested evaluation module for the TPS562246 synchronous buck converter, supporting 4.2V–17V input and delivering up to 2A continuous output current at 1.05V in FCCM mode with 8 mVPP output ripple at 2A load and 12V input.
For engineers reviewing the TPS562246EVM datasheet, TPS562246EVM pinout, TPS562246EVM application, or TPS562246EVM equivalent, this module enables rapid validation of D-CAP3™ control loop performance, load transient response (0.2A–1.8A step), startup/shutdown timing, and low-ESR ceramic capacitor compatibility in power supply design.
Technical Context
The TPS562246EVM implements the TPS562246 IC's fixed-frequency continuous conduction mode (FCCM) operation at 1.2 MHz, optimized for fast transient response without external compensation using POSCAP, SP-CAP, or ceramic output capacitors.
It features adaptive on-time D-CAP3™ control architecture, 0.6V–7V programmable output voltage via resistor divider (R4/R5), and integrated enable control (JP1 shunt), with test points (TP2/TP3/TP8/TP9) for VIN, VOUT, switch node, and EN monitoring under real-world load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.2V to 17V - supports wide industrial and consumer DC bus inputs including 5V, 12V, and 15V rails. |
| Output Voltage Set Point | 1.05V - factory-configured for typical processor core or SoC I/O rail; adjustable via R4/R5 feedback divider. |
| Max Continuous Output Current | 2A - validated with thermal management using 2-oz copper PCB layers and shielded 1.2µH inductor (Wurth 74438357012). |
| Switching Frequency | 1.2 MHz nominal - enables compact magnetics and high-density layout while maintaining efficiency above 85% at mid-load. |
| Output Ripple (12VIN, 2A) | 8 mVPP - measured AC-coupled at 1 µs/div, confirming low-noise regulation suitable for noise-sensitive analog or RF subsystems. |
| Overcurrent Limit | 2.8A - provides robust short-circuit protection without latch-off, allowing safe recovery after fault clearance. |
| Control Mode | FCCM - ensures constant frequency operation across full load range, simplifying EMI filtering and system-level timing predictability. |

FAQ
What is the primary function of the TPS562246EVM?
The TPS562246EVM is an evaluation module for the TPS562246 synchronous buck converter, enabling engineers to validate its FCCM-mode performance-including output ripple (8 mVPP at 2A), load transient response, startup behavior, and D-CAP3™ control loop stability-without designing a custom PCB. It ships fully assembled with test points, input/output connectors, and documented measurement procedures per SLUUCZ0 user's guide.
How does the TPS562246EVM differ from the TPS562243EVM?
The TPS562246EVM evaluates the FCCM-mode variant of the TPS56224x family, while the TPS562243EVM evaluates the Eco-mode variant. Both share identical hardware layout, input/output ranges (4.2V–17V, 0–2A), and 1.05V default output, but differ in light-load behavior: TPS562246EVM maintains fixed 1.2 MHz switching under all loads, whereas TPS562243EVM skips pulses in Eco-mode to improve light-load efficiency. Load transient waveforms (Figures 3-1 vs. 3-2) and ripple measurements (Figures 3-7–3-9) are separately characterized for each.
Can the output voltage of the TPS562246EVM be adjusted?
Yes, the TPS562246EVM output voltage is adjustable from 0.6V to 7V by modifying the feedback resistor divider (R4 and R5). The default 1.05V setting uses R4 = 7.5 kΩ and R5 = 10.0 kΩ; Equation 1 in the SLUUCZ0 user's guide provides the exact calculation. TI recommends 1% tolerance resistors and cautions against excessively high values due to FB input current errors and noise susceptibility.
What test points are available on the TPS562246EVM for debugging?
The TPS562246EVM provides dedicated test points: TP2 (VIN monitor), TP3 (VOUT monitor), TP8 (switch node), TP9 (EN signal), TP6/TP10 (GND references), and TP11 (loop response measurement). These allow direct oscilloscope probing of key signals without soldering, supporting validation of startup timing, ripple, transient response, and control loop stability per Figures 3-3 through 3-9 in the SLUUCZ0 documentation.
Is the TPS562246EVM FCC-certified for emissions testing?
No, the TPS562246EVM is not FCC-certified. Per TI's standard EVM terms, it is intended solely for R&D evaluation-not final product integration-and lacks full EMC compliance certification. Users must perform their own emissions testing on end-product designs incorporating the TPS562246 IC; the EVM serves only to characterize electrical performance (e.g., ripple, transients) under controlled lab conditions as documented in SLUUCZ0.
