Design, optimize, and simulate according to requirements
Capable of designing not only power but also FPGA, LED, sensors, battery chargers, and more

Designing complex power supply devices in industrial, automotive, telecommunications equipment and various other fields is not an easy task even for experienced engineers.

Power devices are fundamentally applied to all systems and have extremely diverse applications. They are essential components in the operation of all systems including smartphones, telecommunications equipment, display devices, automobiles, and medical devices. Although used in many places, design is not easy because each application has different power requirements.

There is a tool to alleviate these concerns. It is the Webench Designer tool. Texas Instruments' (TI) Webench Designer is software that provides customized power, lighting, filtering, clocking, and sensing applications in just a few seconds. With this tool, you can design according to unique specifications and perform optimization and simulation. Before proceeding to production, it is possible to optimize the design according to footprint, cost, and efficiency at the system and supply chain levels.

TI's Webench Power Designer can create customized power supply circuits according to requirements. It also provides end-to-end power supply design functionality that saves time during the design phase. If you know the specifications for input voltage, output voltage, and current, you can run electrical simulation to characterize the transient behavior of the design, and thermal simulation is also possible to identify and correct temperature issues. Schematics and PCB layout can be exported directly to CAD tools, saving time and reducing errors.

Webench is available free on the TI website. In addition to power, Webench Designer enables various designs including FPGA, LED, sensors, and battery chargers. The Webench tool suite is divided into tens of thousands of parts. Price and availability sections are updated regularly, and all external components needed for loop compensation are selected with the expected installation area shown in the schematic.

TI's three advanced Webench tools can conveniently export simulations to CAD (Computer-aided design) platforms such as Altium and Cadence Design Systems. In Webench Visualizer, the 'Advanced Options' feature makes it easy to specify complex design matters such as reconfiguration, component limitations, and control design. For the unstable control loop, which is the most difficult aspect of power supply design, the Webench Compensation Designer tool can predict errors in the control loop and automatically correct them. Using manual mode also allows for fine-tuning the control loop.

The Webench Simulation Export tool is a feature that allows users to export power supply circuit schematics to their preferred simulation environment. Without intermediate software, the entire design can be quickly exported to TINA-TI simulator or Altium Designer, Cadence OrCAD and PSpice tools.

Regarding the reliability between test results with Webench and actual testing, TI's Director Lee Myung-sik answered, "If we use electrical simulation as a standard, approximately 95% or more are accurate. Especially if EVB is the standard, they almost match."
