NCP1397ADR2G

High Performance Resonant  Mode Controller with  Integrated High-Voltage  Drivers 开关控制器

The NCP1397ADR2G NCP1397 is a high performance controller that can be utilized  in half bridge resonant topologies such as series resonant, parallel  resonant and LLC resonant converters. It integrates 600 V gate  drivers, simplifying layout and reducing external component count.  With its unique architecture, including a 500 kHz Voltage Controlled  Oscillator whose control mode permits flexibility when an ORing  function is required, the NCP1397 delivers everything needed to build  a reliable and rugged resonant mode power supply.
