High Performance Resonant Mode Controller with Integrated High-Voltage Drivers NCP1397A/B, NCV1397A/B The 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
