CM6565
Noise Free 16 pin Self-Start Interleaved PFC with
180 Degree Phase Shift CRM PFC Controller for 90+/85+
5. Open Control Loop protection/Tri-Fault Detect
Comparator on VFB pin for easy passing the single fault
protection test of the UL1950 regulation.
The CM6565’s interleaved PFC has two PFC controllers,
Master PFC and Slave PFC. The Slave PFC is lagged ~
180 degree phase shift from the Master PFC. Both PFC
controllers consisted of ZCS plus about ZVS functions. It
provides the high efficient of power supply at both full load
and at light load. To input EMI filter, the currents are
overlapping and it looks like a CCM boost system with
double frequency. The ZCS plus about ZVS on feature
reduce the EMI noise further.
It has a superior performance multiplier making the device
capable of working in universal input voltage range
applications with an excellent THD.
The totem pole output stage is capable of driving a power
MOS or IGBT with +500mA source and -1A sink currents.
The device is operating in transition mode and it is
optimized for Electronic Lamp Ballast application, AC-DC
adaptors and SMPS.
