Want to post a buying lead? If you are not a member yet, please select the specific/related part number first and then fill the quantity and your contact details in the "Request for Quotation Form" on the left, and then click "Send RFQ".Your buying lead can then be posted, and the reliable suppliers will quote via our online message system or other channels soon.
The L6598 is manufactured with the BCD OFF LINE technology, able to ensure voltage ratings up to 600V, making it perfectly suited for AC/DC Adapters and wherever a Resonant Topology can be beneficial. The device is intended to drive two Power MOS, 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.
