NCP1395: 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 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.
