Features & Applications

The L6599ATD is a temperature-extended version of the L6599A. It is a double-ended controller specifically designed for the series-resonant half-bridge topology. It provides a 50% complementary duty cycle: the high-side switch and the low-side switch are driven ON/OFF at 180° out-of-phase for exactly the same time interval.

Output voltage regulation is obtained by modulating the operating frequency. A fixed dead-time inserted between the turn-off of one switch and the turn-on of the other 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
  • -300/700 mA high-side and low-side gate drivers with UVLO pull-down
  • DIP-16, SO-16N 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
