Evaluation boards with Texas Instruments\'s TPS40009EVM-001 integrated circuit (IC) are used to evaluate or develop switch-mode power supplies. This IC is intended to be used in both isolated and non-isolated offline AC to DC and DC to DC converter applications. Its features and specifications make it ideal for applications including telecom, consumer, and portable device power supplies.

Application Fields: 

The TPS40009EVM-001 is a 30V input, 4.5A synchronous buck converter that uses the latest Active-Current-Positioning (AC-P) technology. It comes with the 4.5A TPS300009 synchronous buck regulator. This board is ideal for applications including telecom, consumer, and portable device power supplies. Examples of these applications include AC/DC desktop (up to 250 watts) and adapter/charger (up to 150 watts) adaptors, notebook power adapter (up to 120 watts), LCD/LED TVs (up to 150 watts), server power adapters (up to 200 watts), USB PD (Power Data) charging ports, and high current GaN (Gallium Nitride) charging systems for electric vehicles.

Working Principle: 

The TPS40009EVM-001 board consists of an adjustable, synchronous buck regulator powered by the TPS300009 IC. It is designed to enable fast prototyping of high-efficiency offline adaptor/charger and adapter applications. The IC is a synchronous buck converter that uses the latest Active-Current-Positioning (AC-P) technology to reduce both energy loss and ripple current. The board supports a wide range of input voltages, from 15 V down to 0.7 V, and output voltages, from 19 V down to 0.7 V, as well as adjustable switching frequencies from 500 kHz up to 4 MHz. In addition, the IC provides comprehensive system protection features, prevents ripple current, and allows for low standby current.

The board is intended to be used in both isolated and non-isolated offline AC to DC and DC to DC converter applications. It comes with a full suite of tools, including graphical tuning and debugging, firmware examples, and a step-by-step guide, to help engineers easily evaluate performance and optimize design.

The TPS40009EVM-001 board is designed to handle both ac and dc input voltage profiles, supports multi-mode control, and can provide high power factor, low total harmonic distortion, and low standby power consumption. Features included on the board are PFC (power factor correction), active peak current limiting, adjustable operating frequency, positive/negative voltage tracking, and current mode control for improved efficiency. In addition, the board provides a highly flexible, feature-rich design solution to capture signals from the load and fine-tune power performance to achieve efficiency, stability, and power quality targets.

The TPS40009EVM-001 evaluation board is the perfect platform for the development and evaluation of synchronous buck converters. It enables designers to rapidly prototype, tune, and validate AC/DC, CPPD (Compact Power Package Delivery), and electric vehicle charging applications. With its robust feature set and comprehensive debugging support, TPS40009EVM-001 offers an outstanding way to develop reliable, high-efficiency, cost-competitive products.
