TI WEBENCH Integration Summary

Overview

OpenMates uses TI WEBENCH Power Designer to find power converter reference designs from electrical requirements such as input voltage, output voltage, output current, isolation, ambient temperature, and optimization goal.

This integration is reverse-engineered from https://webench.ti.com/power-designer/. It is not an official public API, so it should be monitored and re-tested regularly.

Authentication

  • Type: none observed
  • Vault key name: none
  • API key required: no

Endpoints Used

Search Power Solutions

  • URL: POST https://webench.ti.com/wb6/restapi/power/solutions
  • Purpose: Return ranked power converter reference designs matching requirements.

Schematic Preview

  • URL: GET https://webench.ti.com/wb6/restapi/power/solutions/{solution_id}/schsvg
  • Purpose: Return an SVG schematic preview for a selected solution.
  • Header requirement: send Content-Type: application/json even for GET.

BOM Components

  • URL: GET https://webench.ti.com/wb6/restapi/power/solutions/{solution_id}/bomcomponents
  • Purpose: Return BOM parts, quantities, values, manufacturers, and component limits.
  • Header requirement: send Content-Type: application/json even for GET.

Input Structure

Parameter Type Required Description
vinMin number yes Minimum input voltage in volts
vinMax number yes Maximum input voltage in volts
vout number[] yes Output voltage rails in volts; first skill supports one rail

ambientTemp number no Ambient temperature in deg C, default 30
isIsolated boolean no Whether isolated conversion is required
powerSupply string no dc or ac
optimizationSetting integer no 1 small footprint, 2 low cost, 3 balanced, 4 high efficiency

Output Structure

Field Type Description
id string WEBENCH solution ID used for schematic/BOM follow-ups
rank integer Provider ranking
considerations string Human-readable design description
info.device.partNumber string Specific TI orderable part number
info.device.basePn string TI base product page identifier
info.device.topology string Converter topology
info.bomCost number Estimated BOM cost in USD
info.efficiency number Efficiency as 0-1 ratio
info.footprint number Footprint in mm2
info.frequency number Switching frequency in Hz
info.temperature number Estimated operating temperature in deg C

Pricing

  • Free tier: public web endpoint, no pricing published
  • Paid tier: not applicable
  • Estimated cost: no direct API cost observed; use conservative rate limiting

Limitations

  • Reverse-engineered endpoint, no stability guarantee.
  • TI can change schema, headers, rate limits, or access requirements.
  • Results are reference-design candidates, not complete PCB layouts.
  • Schematic SVG is visual plus metadata, not a formal EDA netlist.
  • Deeper customize/simulation/export endpoints are under /secured and require WEBENCH login tokens.

Scaling Considerations

  • Cache repeated searches by normalized requirement payload.
  • Keep result counts low for chat use (max_results <= 20).
  • Monitor 4xx/5xx rates and schema validation failures.
  • Re-test monthly because this is not an official public API.

Reverse-Engineered Integration Warning

This integration is not based on official TI API documentation. It was derived from the public WEBENCH Power Designer Angular bundle and verified with live requests on 2026-05-23. Treat provider responses as best-effort external data and show component links back to ti.com for source verification.
