Product Overview

The L6599AD is an improved high-voltage Resonant Controller 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 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. To drive the high-side switch with the bootstrap approach, the IC incorporates a high-voltage floating structure able to withstand more than 600V with a synchronous-driven high-voltage DMOS that replaces the external fast-recovery bootstrap diode. The IC enables the designer to set the operating frequency range of the converter by means of an externally programmable oscillator. At light load the IC may enter a controlled burst mode operation that keeps the converter input consumption to a minimum.
  • 50% Duty cycle, variable frequency control of resonant half bridge
  • High-accuracy oscillator
  • 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
  • -300/800mA High-side and low-side gate drivers with UVLO pull-down

Applications

Consumer Electronics, Computers & Computer Peripherals, Communications & Networking, Power Management
