Description

The NCP1399 is a high performance current mode controller for half bridge resonant converters. This controller implements 600 V gate drivers, simplifying layout and reducing external component count. The built−in Brown−Out input function eases implementation of the controller in all applications. In applications where a PFC front stage is needed, the NCP1399 features a dedicated output to drive the PFCcontroller. This feature together with dedicated skip mode technique further improves light load efficiency of the whole application. The NCP1399 provides a suite of protection features allowing safe operation in any application. This includes: overload protection, over−current protection to prevent hard switching cycles, brown−out detection, openoptocoupler detection, automatic dead−time adjust, overvoltage (OVP) and overtemperature (OTP) protections.

Features

  • High−Frequency Operation from 20 kHz up to 750 kHz
  • Current Mode Control Scheme
  • Automatic Dead−time with Maximum Dead−time Clamp
  • Dedicated Startup Sequence for Fast Resonant Tank Stabilization
  • Skip Mode Operation for Improved Light Load Efficiency
  • 0 Off−mode Operation for Extremely Low No−load Consumption
  • Latched or Auto−Recovery Overload Protection
  • Latched or Auto−Recovery Output Short Circuit Protection
  • Latched Input for Severe Fault Conditions, e.g. OVP or OTP
  • Out of Resonance Switching Protection
  • Open Feedback Loop Protection
  • Precise Brown−Out Protection
  • PFC Stage Operation Control According to Load Conditions
  • Startup Current Source with Extremely Low Leakage Current
  • Dynamic Self−Supply (DSS) Operation in Off−mode or Fault Modes
  • Pin to Adjacent Pin / Open Pin Fail Safe

Typical applications

  • Industrial and Medical Power Sources
  • Adapters and Offline Battery Chargers
  • Computing Power Supplies
  • Flat Panel Display Power Converters
