Infineon ICL5101XUMA1, DC-DC Controller

ICL5101 High-Voltage Resonant Controller IC with PFC

The Infineon ICL5101 integrates a half-bridge controller with a PFC stage in a single package. The integration of high and low side drivers reduces the number of required components and simplifies design, enabling use in small form factor designs. All the parameters are adjustable by resistors. The PFC stage operates in CrCM and DCM mode and it supports various 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.
Typical applications include indoor and outdoor LED lighting, bay-lighting, street lighting, parking and garage lighting, office lighting, shop lighting.
