In a typical 1kW SMPS, the new OCC solution has 40% fewer resistors and capacitors,<br />
removes a current transformer and has a 50% smaller PCB area for the PFC control section.<br />
In addition, the IR1150 has a dedicated Over Voltage Protection (OVP) pin to give<br />
greater protection for high <strong>power</strong> systems.<br />
