Infineon ICL5101 PFC-LLC Combo Controller

Postare su novembre 7, 2018

The ICL5101 integrates a half-bridge controller with a PFC stage in a single package. The high level of integration assures a low number of external components, enabling small form factor designs ideal for compact power supplies in lighting applications, such as LED drivers. All operation parameters of the IC are adjustable via simple resistors, being the ideal choice for an affordable and reliable configuration.

A comprehensive set of protection features, including an adjustable external overtemperature protection and capacitive load protection, ensures the detection of fault conditions to increase the system safety.

Features and benefits

  • Constant voltage or constant current control
  • PFC in CCM mode during nominal load and DCM mode in low-load condition down to 0.1% for operation without audible noise
  • High-power quality with PF > 0.96, THD < 10%
  • Allows secondary-side IC dimming down to 1%
  • PFC/LLC combo IC allows the best matching of PFC stage and LLC stage timing control
  • Supports a wide input voltage range from 90–305 V
