L6599DTR Datasheet, PDF (1/36 Pages) STMicroelectronics – High-voltage resonant controller

L6599
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
