Overview: NCP1396A, NCP1396B Product Preview High Performance Resonant Mode Controller featuring High−voltage Drivers
The NCP1396 A/B offers everything needed to build a reliable and rugged resonant mode power supply. Its unique architecture includes a 500 kHz Voltage Controller 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 weles a bootstrapped MOSFET driver for half−bridge applications accepting bulk voltages up to 600 V. Protections featuring various reaction times, e.g. immediate shutdown or timer−based event, brown−out, broken opto−coupler detection etc., contribute to a safer converter design, without engendering additional circuitry plexity. An adjustable deadtime also helps lowering the shoot−through current contribution as the switching frequency increases.
