L6598D Datasheet PDF - ST Microelectronics

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.
