High-voltage resonant controller
Not for new design
Features
■ 50 % duty cycle, variable frequency control of resonant half-bridge
■ High-accuracy oscillator
■ Up to 500 kHz operating frequency
■ Two-level OCP: frequency-shift and latched shutdown
■ Interface with PFC controller
■ Latched disable input
■ Burst-mode operation at light load
■ Input for power-ON/OFF sequencing or brownout protection
■ Non-linear soft-start for monotonic output voltage rise
■ 600 V-rail compatible high-side gate driver with integrated bootstrap diode and high dV/dt immunity
■ -300/800 mA high-side and low-side gate drivers with UVLO pull-down
■ DIP-16, SO-16N packages
