Texas Instruments TPS55332EVM

Overview

TPS55332EVM from Texas Instruments is an evaluation module designed to validate the operation and performance of the TPS55332QPWPQ1 20-pin PowerPAD™ boost regulator IC. It supports input voltages from 3.6 V to 24 V, delivers regulated output up to 50 V, and enables switching frequency configuration from 80 kHz to 2.2 MHz for design verification in DC/DC power conversion applications.

For engineers reviewing the TPS55332EVM datasheet, TPS55332EVM setup, TPS55332EVM board layout, or TPS55332EVM schematic, this EVM provides hands-on validation of boost converter behavior-including sync capability, enable control, EMC filtering, and thermal management via exposed-pad PCB mounting-under real-world load and input conditions.

Technical Context

The TPS55332EVM implements a single-channel non-synchronous boost converter using the TPS55332QPWPQ1 IC in PWP-20 PowerPAD™ package. It includes configurable EN jumper (JP1), SYNC input (J3) for external clock synchronization, and terminal blocks (J1/J2) for input (V_BAT, GND) and output (V_OUT, GND) connections.

Board-level features include a pi-filter input stage, reverse-battery protection diode (D2), 2 oz copper planes on top/bottom layers, and thermal pad soldering requirement for optimal heat dissipation. The EVM operates across 0–40 V input and 2.5–50 V output ranges, with recommended minimum load applied at V_OUT.

FAQ

What is the primary function of the TPS55332EVM?

The TPS55332EVM is an evaluation module that enables engineers to test and characterize the TPS55332QPWPQ1 boost regulator IC under real operating conditions. It provides accessible terminals, jumpers, and layout features-including SYNC input, EN control, and thermal pad mounting-to verify voltage conversion, efficiency, stability, and thermal behavior before final system integration. The TPS55332EVM does not replace the IC but serves as its validated hardware interface.

Can the TPS55332EVM operate outside the 3.6 V–24 V input range?

No-the TPS55332EVM is rated for 3.6 V to 24 V nominal input, with an absolute maximum of 40 V as stated in the User's Guide warnings. Exceeding 40 V risks irreversible damage to the TPS55332QPWPQ1 IC and supporting components. Input voltage must remain within these limits during all testing phases to ensure reliable operation and avoid voiding warranty or safety compliance.

How is the switching frequency configured on the TPS55332EVM?

Switching frequency on the TPS55332EVM is set by the RT resistor (R4 = 200 kΩ) connected to the RT pin of U1, yielding a default frequency within the 80 kHz–2.2 MHz range. An external clock can be applied via J3 (SYNC terminal) to synchronize multiple converters, provided F_sw < F_ext < 2×F_sw. No onboard trimmer or digital interface is present-frequency tuning requires resistor replacement or external clock injection.

Is the TPS55332EVM RoHS-compliant or certified for end-product use?

No-the TPS55332EVM is explicitly designated for engineering development, demonstration, or evaluation only. It is not compliant with EU directives (RoHS, WEEE, CE), FCC Part 15, or UL standards, and TI disclaims suitability for consumer or safety-critical end products. Users must implement full regulatory compliance-including EMC filtering, isolation, and safety certification-in their final design; the TPS55332EVM serves only as a functional reference.

What thermal considerations apply when using the TPS55332EVM?

The TPS55332EVM uses the TPS55332QPWPQ1 in a PWP-20 PowerPAD™ package, which requires soldering the exposed thermal pad to PCB copper for effective heat transfer. The board uses 2 oz copper planes on both sides to dissipate heat, and certain components-including the IC and power inductors-may exceed 85°C during operation. Proper heatsinking, airflow, and load derating are essential to maintain reliability and avoid thermal shutdown or long-term degradation of the TPS55332EVM.
