Variable Frequency Controllers
Minimum EMI, Maximum Efficiency. . .
ON Semiconductor’s variable frequency controllers include quasi-resonant and resonant controllers.
These controllers are used respectively in critical conduction mode quasi-resonant flyback converters
and half bridge resonant LLC converters. These topologies minimize EMI radiation, provide better
magnetic utilization and offer excellent power conversion efficiency - up to 90%. Our variable
frequency controllers combine the advantages of working directly off-line (with our proprietary
VHVIC technology) with the ability to drive an external high-voltage MOSFET of your choice, and
offer you more design flexibility than our competitors.
