NCP1396ADR2G

Product Summary

The NCP1396ADR2G is a high performance resonant mode controller featuring high-voltage driver. The NCP1396ADR2G offers everything needed to build a reliable and rugged resonant mode power supply. Its unique architecture includes a 500 kHz Voltage Controlled Oscillator whose control mode brings flexibility when an ORing function is a necessity, e.g. in multiple feedback paths implementations. Thanks to its proprietary high--voltage technology, the controller welcomes a bootstrapped MOSFET driver for half--bridge applications accepting bulk voltages up to 600 V. The applications of the NCP1396ADR2G include Flat Panel Display Power Converters, High Power AC/DC Adapters for Notebooks, Industrial and Medical Power Sources, Offline Battery Chargers.
