Description

This design shows the power reduction benefits of dynamically switching a load on/off using a load switch. The design guide shows how frequency of switching, duty cycle, and the use of a discharge resistor can have an impact on power consumption.

Features
  • Power consumption benefits when switching a load on/off dynamically
  • Effects of frequency, duty cycle, and load current on power consumption
  • Use of load switch with and without quick output discharge for dynamic switching
  • This design is tested and includes data for each use case
