TPS40200EVM-002 evaluation boards are an integral part of the Texas Instruments (TI) SMPS (switched-mode power supply) family of products. These boards are designed to provide designers with a comprehensive platform to evaluate the performance of the TPS40200EVM-002 switch-mode power supplies. The design of this device simplifies the evaluation process by removing the need for designing a complicated switch-mode power supply circuit from scratch.

The TPS40200EVM-002 is a fan-cooled DC/DC and AC/DC SMPS evaluation board that operates from a wide range of input sources including 5 VDC, 9 VDC, 11 VDC, 12 VDC, 13.5 VDC, and 24 VDC. The board provides a variety of output voltages and currents for evaluating the TPS40200EVM-002 switch-mode power supplys. The board includes several jumpers and test points for parameter selection and monitoring during device evaluation.

TPS40200EVM-002 operates using a voltage-mode control, featuring a two-input, two-output configuration for providing an output voltage of up to 12V /1.1 A. This efficiency is ideal for applications requiring reliable and precise voltage and current regulation. The device operates over a wide temperature range and delivers a minimal ripple & noise output voltage of 16mV p-p at 6V, 12V, and 10A for an output voltage up to 3V. It has an adjustable autotransformer with synchronized PWM and burst mode control.

The device features two main components: an inductor-diode LC (low-current) filter and a pulse-width modulator (PWM) driver. The LC filter is designed to smoothen the output voltage by providing low-frequency components to the switching regulator\'s output. The PWM driver is designed to drive an external power switch, typically a power MOSFET, and the primary purpose of this driver is to generate precise control signals for regulating the output voltage.

In addition, the TPS40200EVM-002 features an adjustable feedback system which provides precise control of the output voltage and current. This feedback system is capable of responding quickly to changes in output voltage and current, thereby ensuring a stable output voltage. The device also features fault protection circuitry which can detect over-voltage, over-current, and short-circuit conditions, thereby improving device reliability.

TPS40200EVM-002 is specifically designed for lower-current applications in harsh environment applications, due to its high efficiency and reliability. This evaluation board is suitable for applications such as PCs, automotive electronics, telecom power systems, lighting, consumer electronics, industrial power systems and instrumentation. This board is ideal for designers who are looking for an efficient and reliable solution for evaluating their power supplies.
