Description
The device is manufactured with the BCD OFF
LINE technology, able to ensure voltage ratings
up to 600 V, making it perfectly suited for AC/DC
Adapters and wherever a resonant topology can
be beneficial. The device is intended to drive two
power MOSFET, in the classical half bridge
topology. A dedicated timing section allows the
designer to set soft start time, soft start and
minimum frequency. An error amplifier, together
with the two enable inputs, are made available. In
addition, the integrated bootstrap diode and the
zener clamping on low voltage supply, reduces to
a minimum the external parts needed in the
applications.
