| - Internally synchronized PFC
and PWM in one IC
- Low total harmonic
distortion
- Reduces ripple current in
the storage capacitor between the PFC and PWM
sections
- Average current, continuous
boost leading edge PFC
- Fast transconductance error
amp for voltage loop
- High efficiency trailing
edge PWM can be configured for current mode or
voltage mode operation
- Average line voltage
compensation with brownout control
- PFC overvoltage comparator
eliminates output "runaway" due to load
removal
- Current fed gain modulator
for improved noise immunity
- Overvoltage protection, UVLO,
and soft start |
