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.
Features
 
  • High Frequency Operation from 50 kHz up to 1.0 MHz
  • Selectable Minimum Switching Frequency with ±3% Accuracy
  • Timer-Based Input with Auto-Recovery Operation for Delayed Event Reaction
  • Adjustable Deadtime from 150 ns to 1.0 µs
  • Startup Sequence via an Adjustable Soft--Start
  • Brown-Out Protection for a Simpler PFC Association
  • Latched Input for Severe Fault Conditions, e.g. Overtemperature or OVP
  • Enable Input for Immediate Event reaction or Simple ON/OFF Control
  • Operational Transconductance Amplifier (OTA) for Multiple Feedback Loops
  • Low Startup Current of 300 µA max
  • Common Collector Optocoupler Connection
Applications
  • LCD/Plasma TV Converters
  • High Power Ac--Dc Adapters for Notebooks
  • Industrial and Medical Power Sources
  • Offline Battery Chargers
