L6599ATD Datasheet, PDF (1/31 Pages) STMicroelectronics – Improved high-voltage resonant controller

L6599AT
Improved high-voltage resonant controller
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
■ -300/700 mA high-side and low-side gate
drivers with UVLO pull-down
■ DIP16, SO16N package
■ Guaranteed for extreme temperature ranges
Applications
■ Street lighting
■ LCD and PDP TVs
■ Desktop PCs, entry-level servers
■ Telecom SMPS
■ High efficiency industrial SMPS
■ AC-DC adapters, open frame SMPS
