L6699D
Enhanced high-voltage resonant controller, STM, SO16N, RoHS
The L6699 is a double-ended controller specific to series-resonant half bridge topology. Both LLC and LCC configurations are supported. It provides symmetrical 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. The deadtime inserted between the turn-off of one switch and the turn-on of the other one is automatically adjusted to best fit the transition times of the half bridge midpoint. To drive the high-side switch with the bootstrap approach, the IC incorporates a high voltage floating structure able to withstand more than 600 V with a synchronous-driven high voltage DMOS that replaces the external fast-recovery bootstrap diode.

Features:
- Symmetrical duty cycle, variable frequency control of resonant half bridge
- Self-adjusting adaptive deadtime
- High-accuracy oscillator
- 2-level OCP: frequency-shift and immediate shutdown
- Interface with PFC controller
- Anti-capacitive-mode protection
- Burst-mode operation at light load
- Input for brownout protection or power-on/off sequencing
- “Safe-start” procedure prevents hard switching at startup
- 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
