Texas Instruments TPS62097QEVM-891

Overview

TPS62097QEVM-891 from Texas Instruments is an evaluation module designed to characterize the TPS62097-Q1 2-A automotive buck converter featuring iDCS-Control architecture, forced PWM mode, and selectable switching frequency (1.5 MHz to 2.5 MHz). It delivers a regulated 1.8-V output from 2.5–6-V input and supports load currents up to 2000 mA. The EVM enables loop response measurement, soft-start time adjustment, and frequency selection for automotive point-of-load applications including gateway and instrumentation cluster power supplies.

For engineers reviewing the TPS62097QEVM-891 datasheet, TPS62097QEVM-891 schematic, TPS62097QEVM-891 test results, or TPS62097QEVM-891 BOM, this page provides verified board-level specifications, jumper configuration guidance, thermal performance data, layout documentation, and application-ready setup instructions - all validated against TI's official SLVUB74 User's Guide.

Technical Context

The TPS62097QEVM-891 implements the TPS62097-Q1 IC in a fixed 1.8-V output configuration using a 3 mm × 3 mm QFN package with wettable flanks. It supports three operating modes via JP2: forced PWM at 1.5 MHz (MODE–PWM), forced PWM at 2.5 MHz (open), and auto PFM/PWM at 2.0 MHz (MODE–PFM/PWM).

Board-level features include dual-input/output sense connections (J1/J2 S+/S−), programmable soft-start via C3 (1 ms default), PG status monitoring on J3, and configurable MODE pin control. Thermal testing confirms stable operation at 5 V_IN, 2 A, PFM/PWM mode with documented junction temperature rise.

FAQ

What is the primary function of the TPS62097QEVM-891?

The TPS62097QEVM-891 is an evaluation module used to validate the electrical performance, thermal behavior, and control-loop stability of the TPS62097-Q1 2-A automotive buck converter. It provides accessible test points, configurable jumpers, and documented test procedures to support design-in decisions for 1.8-V point-of-load applications in vehicles.

How do I configure the TPS62097QEVM-891 for forced PWM mode at 1.5 MHz?

To configure the TPS62097QEVM-891 for forced PWM mode at 1.5 MHz, install jumper JP2 between MODE and PWM pins before enabling the device. Ensure JP1 is set to ON–EN to activate the IC, and verify R4 = 8.2 kΩ as specified in Table 2 of the SLVUB74 User's Guide. This setting locks constant-frequency operation below the AM band.

Can the TPS62097QEVM-891 be used to measure control-loop response?

Yes - the TPS62097QEVM-891 supports loop response measurement after two PCB modifications: cutting traces on the backside per Figure 1 and installing a 1-Ω resistor across the pads. With this setup, a 10-mV_pp AC signal can be injected to characterize phase/gain margins, as demonstrated in Figure 3 of the SLVUB74 guide.

What are the input and output connection methods on the TPS62097QEVM-891?

The TPS62097QEVM-891 uses dual-pin headers J1 and J2: J1 pins 1–2 accept VIN (2.5–6 V), pins 3–4 provide input sense (S+/S−), and pins 5–6 connect to GND; J2 pins 1–2 deliver VOUT (1.8 V), pins 3–4 provide output sense, and pins 5–6 return to GND. All connections are rated for 2 A continuous operation.

Does the TPS62097QEVM-891 support adjustable output voltage?

No - the TPS62097QEVM-891 is configured for fixed 1.8-V output using the TPS62097-Q1 IC and associated feedback resistors (R1/R2). To evaluate adjustable versions, users must replace U1 with the adjustable TPS62097-Q1 variant and modify the feedback network per Section 1.2.1 of SLVUB74.
