Beschreibung

This document is an engineering report describing a 12 V 1.25 A, 9 V 1.65 A, or 5.0 V 2.0 A, output USB charger utilizing devices from the InnoSwitch-CP family of ICs and a CHY100D. The CHY100D provides Quick Charging 2.0 compliance, allowing a powered device to signal the charger to change from 5.0 V to 9 V and 12 V. This design is intended to show the high power density and efficiency that is possible due to the high level of integration while still providing exceptional performance.This document contains the power supply specification, schematic, bill of materials, transformer documentation, printed circuit layout, and performance data.

Merkmale

  • InnoSwitch-CP industry first AC/DC IC with isolated, safety rated integrated feedback
  • Quick ChargeTM 2.0 compliance via single secondary side IC (CHY100D)
  • Backward compatible to USB battery charging specification 1.2
  • All the benefits of secondary side control with the simplicity of primary side regulation
  • Insensitive to transformer variation
  • Same or better transient response as solution with secondary optocoupler
  • Smaller, lower cost output capacitors
  • Built in synchronous rectification for high efficiency
