The WEBENCH environment provides the end-to-end design and prototyping tools you need to create power supplies or DC-DC Converters that meet your design requirements. WEBENCH tools enable designers to solve switching power supply design problems before a prototype is built, alleviating the time and trouble associated with traditional design methods. The WEBENCH toolset can also be used as a device selection tool to find the best voltage regulator, switching regulator, switched capacitor, mosfet controller, or LDO for your application or power supply solution. Many new parts are fully supported such as the NEW! LM2267x, LM2268x, LM315x, and LM20xxx Families of Full-Featured PowerWise® Buck Regulators and Controllers.
WEBENCH Electrical Simulation
After entering your design specifications, the circuit calculator displays the best power IC options, plus recommendations for the surrounding components. Designs will be suggested using buck (step-down), boost (step-up), flyback, inverting, sepic (buck/boost), ldo/linear, or switched-capacitor topologies, depending on your specifications. Switching regulators with voltage mode, current mode, emulated current mode, or hysteretic control methods are supported in both integrated switch voltage regulator or separate mosfet DC-DC controller solutions.
Utilizing SPICE models, WEBENCH provides various test measurements for you to simulate your power supply circuit, such as bode plots, steady state, input transient, load transient, and startup simulations. Through probe points on a schematic display, you can examine waveforms, change component values, and view a history of simulation results to fine-tune your design.
WebTHERM™ Thermal Simulation
Use this tool to simulate the thermal behavior of an electronic printed circuit board (PCB). Define environmental conditions like ambient temperature, board specifications, air flow, and optional heat sink to solve thermal problems customized to your design requirements. WebTHERM then plots a color map of the PCB, allowing you to identify any potentially hot spots on your board.
Build It Features
WEBENCH Designer creates the ideal design values to meet your desired performance parameters. It then selects a bill of materials (BOM) from a database of real world inductors, capacitors, resistors, mosfets, and active components that meet your performance requirements. WEBENCH Designer then optimizes your kit based on hourly feeds of component availability from distributors around the world so that your optimized design can be ordered and shipped the same day you create it. WEBENCH BuildIt provides complete documentation to assemble your design: BOM, schematic, design specifications, and simulation results so you can assemble and test your design as soon as you receive the kit. WEBENCH tools give you the best possible design quickly with real world components so you can have your design operating as soon as possible.
