Overview
1.1
Features
PFC Section
– IEC 1000-3 compliant
– Additional operation mode as auxiliary power supply
– Fast, soft switching totem pole gate drive (1 A)
– Dual loop control (average current and voltage
sensing)
– Leading edge triggered pulse width modulation
– Peak current limitation
– Topologies of PFC preconverter are boost or flyback
– Continuous/discontinuous mode possible
– 94% maximum duty cycle
PWM Section
– Improved current mode control
– Fast, soft switching totem pole gate drive (1 A)
– Soft-start management
– Trailing edge triggered pulse width modulation
– Topologies of PWM converter are feed forward or flyback
– 50% maximum duty cycle to prevent transformer saturation
