Description

The L6598D is a high voltage Resonant Controller. The device is manufactured with the BCD™ offline technology, able to ensure voltage ratings up to 600V and 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. 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.
dV/dt Immunity ±50V/ns in full temperature range
Switching times 80/40ns rise/fall with 1nF load
CMOS shutdown input
Under-voltage lockout
Soft-start frequency shifting timing
Sense op amp for closed loop control or protection
High accuracy current controlled oscillator
Integrated bootstrap diode
Clamping on Vs
ESD sensitive device, take proper precaution while handling the device.
