Features & Applications

The L6599 is a double-ended controller specific for the resonant half-bridge topology. It provides 50 % complementary duty cycle: the high-side switch and the low-side switch are driven ON\OFF 180° out-of-phase for exactly the same time.

Output voltage regulation is obtained by modulating the operating frequency. A fixed deadtime inserted between the turn-OFF of one switch and the turn-ON of the other one guarantees soft-switching and enables high-frequency operation.

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

Applications:

  • LCD and PDP TV
  • Desktop PC, entry-level server
  • Telecom SMPS
  • AC-DC adapter, open frame SMPS
