Improved high-voltage resonant controller - STMicroelectronics
Description
L6599A
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 ■ -300/800 mA high-side and low-side gate drivers with UVLO pull-down ■ DIP16, SO16N package
Applications
■ LCD and PDP TV ■ Desktop PC, entry-level server ■ Telecom SMPS ■ High efficiency industrial SMPS ■ AC-DC adapter, open frame SMPS
