Sense op amp for closed loop control or
protection features
High accuracy current controlled oscillator
Integrated bootstrap diode
Clamping on Vs
Available in DIP16 and SO16 packages
Description
The L6598 device is manufactured with the
Features
BCD™ offline technology, able to ensure voltage
ratings up to 600 V, making it perfectly suited for
High voltage rail up to 600 V
dV/dt immunity ±50 V/ns in full temperature
range
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
Driver current capability: 250 mA source
the designer to set soft-start time, soft-start and
450 mA sink
minimum frequency. An error amplifier, together
Switching times 80/40 ns rise/fall with 1 nF load
CMOS shutdown input
with the two enable inputs, are made available. In
addition, the integrated bootstrap diode and the
Zener clamping on low voltage supply, reduces to
Undervoltage lockout
a minimum the external parts needed in the
Soft-start frequency shifting timing
applications.
