Description

This reference design details how to drive various forms of electronically dimmable glass, including SPD-SmartGlass™ and APD Glass from a car battery. This illustrates how to make a DC/AC inverter using the LM5155-Q1 boost converter with a charge pump, two UCC27712-Q1 half bridge drivers, and a TMS320F2807 microcontroller for PWM creation and system monitoring.

Features
  • 120 Vrms AC output
  • 100mA driving capability
  • Controllable output amplitude for intermediate levels of glass dimming
  • This circuit design is tested and includes gerbers, schematics, and BOM
