L6598D L6598 SOP-16 SMD High Voltage Resonant Controller
DESCRIPTION
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.
