ICL5101
The ICL5101 integrates a half-bridge controller with a PFC stage in a single package. The high level of integration assures a low count of external components, enabling small form factor designs ideal for compact power supplies in lighting applications, such as LED driver.
The PFC stage operates in CrCM and DCM mode, supporting stable operation at low load conditions down to 0.1% of the nominal power. The half-bridge resonant stage – typically in LLC topology – provides high- and low-side gate drive function for discrete MOSFETs rated up to 650 V. Its non-overlap dead time is adaptive from 500 ns ... 1.0 μs.
All operation parameters of the IC are adjustable by simple resistors, this being the ideal choice for cheap and reliable configuration. A comprehensive set of protection features incl. an adjustable external over temperature protection and capacitive load protection ensures the detection of fault conditions to increase the system safety.
