Texas Instruments TPS62220EVM-014

Overview

TPS62220EVM-014 from Texas Instruments is an evaluation module built around the TPS62220DDC adjustable-output buck converter, configured to deliver a regulated 1.8 V at up to 400 mA across a 2.5 V–6 V input range. It features SOT23-5 packaging, CDRH2D18/HP-4.7 µH inductor, and ceramic output capacitance for compact DC/DC conversion validation in portable power applications.

For engineers reviewing the TPS62220EVM-014 datasheet, TPS62220EVM-014 pinout, TPS62220EVM-014 application, or TPS62220EVM-014 equivalent, this EVM supports rapid prototyping of low-voltage, high-efficiency step-down supplies in space-constrained designs such as handheld instrumentation, battery-powered sensors, and embedded microcontroller power rails.

Technical Context

The TPS62220EVM-014 implements a synchronous buck topology using the TPS62220DDC IC, which integrates MOSFETs and operates with fixed 2.25 MHz switching frequency. Its feedback network (R1 = 475 kΩ, R2 = 182 kΩ) sets the output to 1.8 V, and the enable jumper (JP1) provides hardware-level on/off control tied to VIN or GND.

Designed for laboratory evaluation only, the board uses optimized layout practices-including isolated high-frequency switching nodes and short current loops-to minimize noise coupling into the FB path. Input and output connections are via 2-pin headers (J1–J4), with thermal management relying on PCB copper area rather than heatsinking.

FAQ

What is the primary function of the TPS62220EVM-014?

The TPS62220EVM-014 is an evaluation module designed to demonstrate and validate the performance of the TPS62220DDC synchronous buck converter. It provides a ready-to-use 1.8-V, 400-mA regulated output from a 2.5–6-V input, enabling engineers to verify efficiency, transient response, and layout best practices before integrating the IC into their own designs. The TPS62220EVM-014 includes all necessary passives, enable control, and test points for immediate lab testing.

Can the TPS62220EVM-014 be used for production applications?

No - the TPS62220EVM-014 is explicitly intended for engineering development and evaluation purposes only. Texas Instruments states it is not fit for commercial use due to lack of end-product safety measures, regulatory certifications (e.g., FCC, CE, UL), and full manufacturing validation. For production, designers must implement the TPS62220DDC IC on a custom PCB meeting applicable safety, EMC, and reliability standards. The TPS62220EVM-014 serves solely as a reference for that implementation.

What input voltage range is safe for the TPS62220EVM-014?

The TPS62220EVM-014 must operate strictly within 2.5 V to 6 V input voltage. Exceeding 6 V risks irreversible damage to the TPS62220DDC IC and supporting components; the absolute maximum rating is 7 V but operation above 6 V violates the device's specified operating conditions. Input leads should be twisted and kept short to minimize noise and voltage drop. The TPS62220EVM-014 user guide explicitly warns against exceeding this range.

How is output voltage set on the TPS62220EVM-014?

The TPS62220EVM-014 uses a fixed resistor divider (R1 = 475 kΩ, R2 = 182 kΩ) connected to the FB pin of the TPS62220DDC to set the output to 1.8 V. This configuration follows the IC's internal 0.6-V reference and the formula V_OUT = 0.6 × (1 + R1/R2). No external adjustment is provided on the board - the TPS62220EVM-014 is pre-configured for 1.8 V, unlike the base TPS62220DDC which supports adjustable outputs via external resistors.

Does the TPS62220EVM-014 include overcurrent or thermal protection?

The TPS62220EVM-014 relies entirely on the built-in protection features of the TPS62220DDC IC, which includes cycle-by-cycle current limiting and thermal shutdown. However, the evaluation module itself has no additional current-sense circuitry, fault reporting, or external thermal monitoring. Users must observe the 400-mA output limit and ensure adequate airflow, as some components (e.g., the inductor and IC) may exceed 125°C during normal operation - a condition explicitly noted in the TPS62220EVM-014 User's Guide.
