Fonctionnalités et applications

The NCP1396 is a 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 Controlled 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 welcomes 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 complexity. An adjustable deadtime also helps lowering the shoot−through current contribution as the switching frequency increases.

Key Features:

  • High−frequency Operation from 50 kHz up to 500 kHz
  • 600 V High−Voltage Floating Driver
  • Selectable Minimum Switching Frequency with ±3% Accuracy
  • Adjustable Deadtime from 100 ns to 2 µs.
  • Startup Sequence via an Adjustable Soft−start
  • Brown−out Protection for a Simpler PFC Association
  • Latched Input for Severe Fault Conditions, e.g. Over Temperature or OVP
  • Timer−based Input with Auto−recovery Operation for Delayed Event Reaction
  • Enable Input for Immediate Event Reaction or Simple ON/OFF Control
  • VCC Operation up to 20 V
  • Low Startup Current of 300 µA
  • 1 A / 0.5 A Peak Current Sink / Source Drive Capability
  • Common Collector Optocoupler Connection for Easier ORing
  • Internal Temperature Shutdown
  • B Version features 10 V VCC Startup Threshold
  • These are Pb−Free Devices


  • Improved fault handling and robustness
  • Prevents shoot-through currents and allows for optimization based on MOSFET characteristics
  • Prevents damage from current spikes and startup and reduces EMI
  • Protects against input voltage drops and simplifies PFC association


  • Flat Panel Display Power Converters
  • High Power AC/DC Adapters for Notebooks
  • Industrial and Medical Power Sources
  • Offline Battery Chargers
