Description
The LED Resonant controller ICL5101
is designed to control resonant converter
topologies. The PFC stage operates in CrCM and
DCM mode, supporting low load conditions.
Integrated high and low side drivers assure a low
count of external components, enabling small form
factor designs.
ICL5101 parameters are adjusted by simple
resistors only, this being the ideal choice to ease
the design-in process. A comprehensive set of
protection features ensures that the LED driver
detects fault conditions, protecting both the LED
driver and the LED load. Figure 1shows a typical
application circuit of a 110 W constant voltage LED
driver.
