9.1 Application Information

The TPSM63602 only requires a few external components to convert from a wide range of supply voltages to a fixed output voltage. The following section describes the design procedure to configure the TPSM63602 power module. To expedite and streamline the design process, WEBENCH® online software is available to generate complete designs, leveraging iterative design procedures and access to comprehensive component databases. To expedite and streamline the design process for a TPSM63602-based regulator, a comprehensive TPSM63602 quickstart calculator.

As mentioned previously, the TPSM63602 also integrates several optional features to meet system design requirements, including the following:

  • Precision enable with hysteresis
  • External adjustable UVLO
  • Adjustable SW node slew rate
  • A power-good indicator

The following application circuits show the TPSM63602 configuration options suitable for several application use cases. Refer to the TPSM63603EVM User's Guide for more detail.
