Infineon Technologies ICL8201

Description

The ICL8201 is a cascode structure current mode controller for non-isolated floating buck topologies. The cascode topology enables lower system cost and higher system efficiency.Lower system cost: -No auxiliary winding is required to power the IC-No high-voltage start up depletion MOSFET is required, fast time to light can be achieved inherently with cascode topologyHigher System Efficiency and Reliability: -No start up resistor is required that would cause significant losses during the entire operation. These losses can be eliminated by using the cascode topology which increases the system efficiency and lifetime.
