Texas Instruments TPS62A01QEVM-270

Overview

TPS62A01QEVM-270 from Texas Instruments is an evaluation module designed to validate the operation of the TPS62A01-Q1 automotive synchronous buck converter, delivering up to 1-A output at 1.8 V from a 2.5–5.5-V input. It supports adjustable output voltage via feedback resistor divider and enables functional verification of power-save mode, forced PWM mode (via companion TPS62A01AQEVM-270), and high-frequency 2.4-MHz switching in compact SOT563 packaging.

For engineers reviewing the TPS62A01QEVM-270 datasheet, TPS62A01QEVM-270 hardware setup, TPS62A01QEVM-270 schematic, or TPS62A01QEVM-270 BOM integration, this EVM provides validated PCB layout, jumper-controlled EN/PG configuration, dual-voltage sense interfaces (J1/J2), and documented component-level modifiability for automotive DC-DC design validation.

Technical Context

The TPS62A01QEVM-270 implements a fixed 1.8-V output configuration using the TPS62A01QDRLRQ1 IC in PFM/PWM hybrid mode, with input voltage sensing (J1 pins 3–4), output voltage sensing (J2 pins 3–4), and configurable power-good signaling via JP3. Its 4-layer PCB layout includes dedicated signal layers for SW, FB, and PG routing, minimizing noise coupling in high-frequency buck operation.

Hardware modifiability includes on-board provisions for adding input/output capacitors (C4/C5, C8–C10), feedforward capacitor C11 (33 pF), and resistor-divider adjustment (R1/R2) to support alternate output voltages - all while maintaining compliance with TI's recommended stability criteria for the TPS62A01-Q1 family.

FAQ

What is the primary function of the TPS62A01QEVM-270?

The TPS62A01QEVM-270 is an evaluation module used to test and validate the electrical performance, thermal behavior, and system integration of the TPS62A01-Q1 automotive buck converter. It provides a ready-to-use platform with preconfigured 1.8-V output, jumper-controlled enable/power-good signals, and accessible test points for input/output voltage and current measurement - enabling rapid verification before custom PCB design.

Can the TPS62A01QEVM-270 be used to evaluate both TPS62A01-Q1 and TPS62A01A-Q1 devices?

Yes - the TPS62A01QEVM-270 board layout and schematic are explicitly validated for both the TPS62A01-Q1 (PFM/PWM auto-mode) and TPS62A01A-Q1 (forced PWM only) variants. The EVM accommodates either IC in the same SOT563 footprint, and its documentation confirms identical mechanical and electrical compatibility for both parts, including shared jumper configurations and sense point placements.

How do I configure the TPS62A01QEVM-270 for different output voltages?

To change the output voltage on the TPS62A01QEVM-270, replace resistors R1 (80.6 kΩ) and R2 (40.2 kΩ) with values calculated using the TPS62A01-Q1 feedback equation: VOUT = 0.6 V × (1 + R1/R2). The EVM includes solder pads for alternate resistor placement, and the user's guide specifies that output capacitance must remain within the device data sheet's recommended range to ensure stability at the new voltage setting.

What are the key hardware interfaces on the TPS62A01QEVM-270?

The TPS62A01QEVM-270 features J1 (input: VIN, S+/S–, GND), J2 (output: VOUT, S+/S–, GND), JP1 (EN ON/OFF), JP2 (PG pullup voltage selection), and JP3 (PG/GND header). These interfaces allow precise input/output voltage monitoring, controlled startup/shutdown, configurable power-good signaling, and flexible system-level integration - all documented in the SLUUCV4 user's guide with pin-specific test point locations.

Is the TPS62A01QEVM-270 compliant with automotive EMC requirements?

The TPS62A01QEVM-270 itself is not certified for automotive EMC standards, but it incorporates design features aligned with robust automotive evaluation: dual-point voltage sensing (reducing noise pickup), feedforward capacitor C11 (33 pF) for loop compensation, and EMI-reduction capacitors C13/C14 between sense lines. Final EMC compliance must be verified on the target application board per ISO 11452 and CISPR 25 requirements.
