Product details
Overview
TPS65279VTEVM from Texas Instruments is an evaluation module designed to demonstrate and validate the dual-output, I²C-programmable buck converter PMIC TPS65279V. It supports input voltages from 4.5 V to 18 V, delivers up to 5 A per channel at programmable outputs (1.0 V and 1.1 V default), and enables real-time voltage control via USB-connected GUI software with I²C interface.
For engineers reviewing the TPS65279VTEVM datasheet, TPS65279VTEVM hardware setup, TPS65279VTEVM software operation, or TPS65279VTEVM BOM integration, this EVM provides full access to VID-controlled output regulation, mode selection (PWM/PSM/current-share), external frequency synchronization (200 kHz–1.6 MHz), and register-level configuration of the underlying TPS65279V PMIC.
Technical Context
The TPS65279VTEVM implements the TPS65279V power management IC in a fully assembled, test-ready PCB layout with dual synchronous buck converters, on-board I²C address jumpers (JP7), mode-select jumpers (JP8), enable controls (JP1/JP2), and SYNC input support. It includes 10-pin I²C interface header JP15 and dedicated test points for LX1/LX2, VOUT1/VOUT2, and ground references.
Hardware design supports bench validation under defined conditions: 4.5–18 V input, 7 A supply capability, and external function generator for SYNC signal injection. The board integrates two 3.3 µH power inductors (L1/L2), 22 µF ceramic output capacitors (C20/C28 series), and configurable resistor dividers for non-I²C voltage programming - all aligned with the TPS65279V's external compensation and soft-start architecture.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5 V to 18 V - supports wide-input industrial and automotive power rails. |
| Output Channels | Dual independent buck outputs (VOUT1, VOUT2) - enables split-rail or multi-core processor supply. |
| Max Output Current | 5 A per channel - sufficient for high-performance SoCs or FPGA core rails. |
| I²C Interface | Configurable address (0x60H/0x61H/0x62H via JP7) and 3.3 V/6.25 V selectable I/O power (JP9) - ensures compatibility with host controller logic levels. |
| Switching Frequency | 200 kHz to 1.6 MHz (externally synchronized) - allows EMI optimization and inductor size trade-offs. |
| Control Modes | Forced PWM, auto PSM-PWM, and current-share modes (selected via JP8) - adapts efficiency vs. transient response per application need. |
| Software Interface | GUI-based Windows application with register-level read/write access - enables rapid prototyping and parameter sweep testing. |

FAQ
What is the primary purpose of the TPS65279VTEVM?
The TPS65279VTEVM is an evaluation module built to demonstrate and validate the functionality of the TPS65279V dual-output buck converter PMIC. It provides immediate access to I²C-controlled voltage regulation, mode selection, and real-time register configuration via a Windows GUI, enabling rapid power architecture prototyping without custom PCB development.
Does the TPS65279VTEVM require external hardware to operate?
Yes - the TPS65279VTEVM requires a 4.5–18 V, 7 A DC power supply connected to J1, a Windows PC with USB port, and the included USB-TO-GPIO interface box. The GUI software communicates with the TPS65279VTEVM through JP15 using I²C, and optional SYNC signal generation requires an external function generator.
How are output voltages configured on the TPS65279VTEVM?
Output voltages on the TPS65279VTEVM are configured either via I²C using the GUI software (default 1.0 V for VOUT1 and 1.1 V for VOUT2) or by external resistor dividers. The board includes jumpers JP1 and JP2 for enable control, and JP7 sets the I²C address to match software communication settings for reliable TPS65279VTEVM operation.
Can the TPS65279VTEVM be used to evaluate switching frequency effects?
Yes - the TPS65279VTEVM supports externally synchronized switching frequencies from 200 kHz to 1.6 MHz via the SYNC pin. This allows engineers to assess efficiency, thermal behavior, and EMI performance across the full operational range of the underlying TPS65279V, using a function generator connected to the designated test point.
Is the TPS65279VTEVM compatible with other TI PMIC evaluation tools?
The TPS65279VTEVM uses TI's standardized USB-TO-GPIO interface and GUI framework, enabling consistent workflow with other TI EVMs like the TPS65988EVM or TPS650861EVM. However, its hardware layout, jumper configuration, and register map are specific to the TPS65279V, so software and BOM files must be used exclusively with the TPS65279VTEVM.
