L6598D

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
