The Texas Instruments TPS40075EVM-001 is an evaluation board used to evaluate and design off-line SMPS (Switching Mode Power Supply) using the TPS40075 device. It is part of a family of evaluation boards from Texas Instruments that are used to evaluate DC/DC and AC/DC switching power supplies. The TPS40075 is a low-cost, multi-mode, line-powered SMPS controller designed to accommodate a wide range of power supply designs. Its features include pulse frequency modulation, inductor current limit protection, and advanced valley switching for higher efficiency across a wide range of load conditions. It has been designed to facilitate the evaluation and design of lean-mode topologies in compact form factors with lower-power design goals. The TPS40075EVM-001 board is capable of delivering up to 9A continuous and up to 12A pulsed output current from an input voltage in the range of 5V to 30V. It features a wide-ranging power supply design with a minimum input cap and multiple outputs. It supports multiple operating modes including line-fed forward mode, pulse width modulation (PWM) discontinuous conduction mode (DCM), and valley switching (VSM). The supported topologies are forward-mode quasi-resonant, and active-clamp-forward with valley switching. The board has a high efficiency rating and low profile design that can be used for both AC-DC and DC-DC applications. It is also equipped with several features to enhance user convenience, including an on-board LED power indicator, an external enable pin, and a power-good indicator. Additionally, the integrated control loop of the TPS40075 provides wide-range voltage and current loop protection, allowing the board to operate safely and reliably in harsh environments. In its forward-mode quasi-resonant (FMQR) design, the TPS40075EVM-001 produces a highly efficient power supply with no acoustic noise. The active-clamp-forward (ACF) enables the system to further increase efficiency and reduce no-load losses. Additionally, the active valley switching (VSM) allows for a further increase in peak efficiency. The TPS40075EVM-001 evaluation board is ideal for use in a wide range of applications, including but not limited to, electric vehicle charging systems, white goods, automotive, portable consumer electronics, power distribution, LED lighting, and medical power supplies. Its design makes it suitable for low-cost, low-power designs while still providing a high-efficiency rating and advanced control features. In conclusion, the TPS40075EVM-001 is an ideal evaluation board for the designer who is looking for a low-cost, low-power, and efficient solution for their DC/DC and AC/DC switching power supply needs. The wide range of operating modes and features available make it extremely versatile, while the integrated control loop provides excellent protection and enables thorough testing of the TPS40075 device.
