The NCP1395A/B offers everything needed to build a reliable and rugged resonant mode power supply. Its unique architecture includes a 1 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 opto-coupler 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 on-board operational transconductance amplifier allows for various configurations including constant output current working mode or traditional voltage regulation.
