NCP1397ADR2G Datasheet PDF - ON Semiconductor

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  rivers, 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.
