Texas Instruments TPS62175EVM-098

Overview

TPS62175EVM-098 from Texas Instruments is an evaluation module designed to validate the operation of the TPS62175 500-mA synchronous buck converter IC. It accepts 4.75 V to 28 V input and delivers a regulated 3.3 V ±30 mV output at up to 500 mA, supporting design verification in industrial power supply and embedded system applications.

For engineers reviewing the TPS62175EVM-098 datasheet, TPS62175EVM-098 schematic, TPS62175EVM-098 BOM, or TPS62175EVM-098 test results, this EVM provides validated hardware for efficiency measurement, thermal characterization, loop response analysis, and sleep-mode functionality validation under real-world load and input conditions.

Technical Context

The TPS62175EVM-098 implements the adjustable-output TPS62175DQC (2 mm × 3 mm WSON-10) configured with R1 = 1.21 MΩ and R2 = 383 kΩ to set VOUT = 3.3 V. Input and output sense headers (J2, J5), enable/sleep jumpers (JP1, JP2), and PG pullup selection (JP3) provide full functional control without soldering.

Test points (TP1), optional loop response modification pads, and provisioned capacitor locations (C3, C4, C6) support dynamic performance analysis and design iteration. Thermal performance is characterized at VIN = 12 V and 500 mA load, with peak efficiency reaching 92.2% at VIN = 4.75 V.

FAQ

What is the primary function of the TPS62175EVM-098?

The TPS62175EVM-098 is an evaluation module built around the TPS62175 synchronous buck converter IC. Its primary function is to enable rapid functional validation, efficiency testing, thermal characterization, and loop stability analysis of the TPS62175 in real operating conditions. Engineers use the TPS62175EVM-098 to verify voltage regulation accuracy, transient response, sleep-mode behavior, and PCB layout effectiveness before integrating the TPS62175 into end-product designs.

Does the TPS62175EVM-098 support both fixed and adjustable output versions of the TPS62175?

Yes, the TPS62175EVM-098 supports both versions. It ships with the adjustable TPS62175DQC configured for 3.3 V output using resistor dividers R1 and R2. To evaluate a fixed-output variant, users can replace U1 with a fixed-voltage TPS62175 part and modify R1/R2 per the user's guide-specifically installing a 0-Ω resistor at R2 and removing R1. The board layout accommodates this change without redesign.

How do I configure the TPS62175EVM-098 for sleep mode operation?

Sleep mode on the TPS62175EVM-098 is controlled via jumper JP2. Place the supplied jumper across the ON and SLEEP pins to activate sleep mode, reducing quiescent current and enabling ultra-low-power standby states. In sleep mode, the TPS62175EVM-098 maintains output regulation while minimizing power draw-critical for battery-powered applications where the TPS62175EVM-098 serves as a reference for low-I_Q design validation.

Can I measure the control loop response using the TPS62175EVM-098?

Yes, the TPS62175EVM-098 supports loop response measurement via two documented modifications: (1) install a 10-Ω resistor across designated pads on the back side, and (2) cut the trace between the VOS pin via and output capacitor C2. Once modified, a 10-mV_pp AC signal can be injected to characterize phase margin and gain crossover-enabling direct validation of the TPS62175's internal compensation network using standard network analyzers.

What are the key connectors and test points on the TPS62175EVM-098?

The TPS62175EVM-098 features J1 (VIN), J3 (GND), J4 (VOUT), and J6 (GND) for main power connections; J2 and J5 for remote input/output voltage sensing; J7 for PG monitoring; and TP1 for probing the switch node. Jumpers JP1 (EN), JP2 (SLEEP), and JP3 (PG pullup) provide configurable control. These interfaces allow precise measurement, functional toggling, and integration into automated test setups without soldering or board modification.
