Texas Instruments TPS65288EVM

Overview

TPS65288EVM from Texas Instruments is an evaluation module designed to demonstrate and validate the TPS65288 high-current PMIC - a triple synchronous buck converter with two integrated USB power switches. It supports 4.5–18 V input, delivers 1.2 V/3 A (Buck1), 1.8 V/2 A (Buck2), and 3.3 V/2 A (Buck3) outputs, and enables rapid prototyping of multi-rail power architectures for embedded systems.

For engineers reviewing the TPS65288EVM datasheet, TPS65288EVM test setup, TPS65288EVM jumper configuration, or TPS65288EVM schematic and layout, this module provides full access to enable/disable sequencing, forced PWM mode, PGOOD monitoring, and USB switch fault signaling - critical for validating power delivery in industrial and computing applications.

Technical Context

The TPS65288EVM implements the full feature set of the TPS65288 PMIC, including independent enable control for each buck converter (JP3, JP11, JP20), configurable forced-PWM operation (JP25), and dual USB switch enable/fault monitoring (JP5, JP34, JP26, JP35). All three buck regulators operate at 500 kHz switching frequency on the EVM.

Test points (e.g., TP4 for Vin, TP14/TP17/TP37 for Vout1/Vout2/Vout3, TP32/TP33/TP31/TP30 for USB1/USB2 I/O) provide direct access to key nodes. The board uses QFN-40 footprint for U1 (TPS65288) and includes terminal blocks (J1–J6), jumpers, and ceramic/tantalum capacitors optimized per TI's design guidelines.

FAQ

What is the primary function of the TPS65288EVM?

The TPS65288EVM is an evaluation module that demonstrates the TPS65288 triple-buck PMIC with integrated USB power switches. It allows engineers to verify output regulation, sequencing behavior, USB switch control, and fault response under real-world load and input conditions - without designing a custom PCB. The TPS65288EVM includes all necessary passive components, test points, and jumper-based configuration for immediate bench testing.

How do I configure the buck converters on the TPS65288EVM?

Each buck converter on the TPS65288EVM is enabled via dedicated jumpers: JP11 for Buck1, JP20 for Buck2, and JP3 for Buck3. Jumper placement to V3V enables immediate start-up; placement to GND disables the converter. External enable signals can also be applied to the ENx headers. The TPS65288EVM user guide specifies exact jumper locations and sequencing options for controlled power-up sequences.

Does the TPS65288EVM support forced PWM mode?

Yes, the TPS65288EVM supports forced PWM operation using jumper JP25. When fitted to V3V, it forces all buck converters into continuous PWM mode regardless of load; when fitted to GND, it enables automatic PFM/PWM transition. This capability allows direct comparison of light-load efficiency versus ripple/noise performance - a key verification step for the TPS65288EVM in battery-sensitive or noise-critical applications.

Can the TPS65288EVM be used to evaluate USB power switch functionality?

Yes, the TPS65288EVM integrates two USB power distribution switches with dedicated enable (JP34 for USB1, JP5 for USB2) and fault indicator (JP35 for USB1_nFAULT, JP26 for USB2_nFAULT) jumpers. Test points TP32/TP33 and TP31/TP30 provide direct access to USB input/output voltages, enabling validation of overcurrent protection, enable timing, and fault recovery behavior - essential for USB-compliant system design using the TPS65288EVM.

Where are the main test points located on the TPS65288EVM?

Main test points on the TPS65288EVM include TP4 (Vin), TP14 (Vout1/Buck1), TP17 (Vout2/Buck2), TP37 (Vout3/Buck3), TP32/TP33 (USB1 input/output), and TP31/TP30 (USB2 input/output). Ground test points (TP1–TP3, TP5–TP7) are placed adjacent to voltage test points to minimize measurement noise. These locations are labeled on the board silkscreen and documented in Section 4.2 of the TPS65288EVM User's Guide (SLVU897).
