NCP1395B Datasheet High Performance Resonant Mode Controller

Manufacturer: onsemi

Overview: NCP1395A/B High Performance Resonant Mode Controller The NCP1395A/B offers everything needed to build a reliable and rugged resonant mode power supply. Its unique architecture includes a 1.0 MHz Voltage Controller Oscillator whose control mode brings flexibility when an ORing function is a necessity, e.g. in multiple feedback paths implementations. Protections featuring various reaction times, e.g. immediate shutdown or timer−based event, brown−out, broken optocoupler detection etc., contribute to a safer converter design, without engendering additional circuitry complexity. An adjustable deadtime also helps lowering the shoot−through current contribution as the switching frequency increases. Finally, an onboard operational transconductance amplifier allows for various configurations, including constant output current working mode or traditional voltage regulation.

This datasheet includes multiple variants, all published together in a single manufacturer document.
