L6598 DIP-16

HIGH VOLTAGE RESONANT CONTROLLER
PMIC Solutions High Volt Reson Cont

Description
The L6598 device is manufactured with the
BCD™ offline 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 MOSFETs, 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
