NCP1397ADR2G

Product Summary

The NCP1397ADR2G is a high performance controller that can be utilized in half bridge resonant topologies such as series resonant, parallel resonant and LLC resonant converters. The NCP1397ADR2G 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 device everything needed to build a reliable and rugged resonant mode power supply. The NCP1397ADR2G provides a suite of protection features with configurable settings to optimize any application. The applications of the NCP1397ADR2G include Flat Panel Display Power Converters, High Power ac-dc Adapters for Notebooks, Computing Power Supplies, Industrial and Medical Power Sources, Offline Battery Chargers.
