Device description
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 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 one
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 start-up, to prevent uncontrolled inrush current, the switching frequency starts from a
programmable maximum value and progressively decays until it reaches the steady-state
value determined by the control loop. This frequency shift is non linear to minimize output
voltage overshoots; its duration is programmable as well.
The IC can be forced to enter a controlled burst-mode operation at light load, so as to keep
converter's input consumption to a minimum.
IC's functions include a not-latched active-low disable input with current hysteresis useful for
power sequencing or for brownout protection, a current sense input for OCP with frequency
shift and delayed shutdown with automatic restart.
A higher level OCP latches off the IC if the first-level protection is not sufficient to control the
primary current. Their combination offers complete protection against overload and short
circuits. An additional latched disable input (DIS) allows easy implementation of OTP and/or
OVP.
An interface with the PFC controller is provided that enables to switch off the pre-regulator
during fault conditions, such as OCP shutdown and DIS high, or during burst-mode
operation.
