NCP1339: High Frequency Quasi-Resonant Controller

Description: The NCP1339 is a highly integrated quasi-resonant ...
  • The NCP1339 is a highly integrated quasi-resonant flyback controller capable of controlling rugged and high-performance off-line power supplies as required by adapter applications. With an integrated active X-cap discharge feature and power savings mode, the NCP1339 can enable no-load power consumption below 10 mW for 65 W notebook adapters. The quasi-resonant current-mode flyback stage features a proprietary valley-lockout circuitry, ensuring stable valley switching. This system works down to the 6th valley and toggles to a frequency foldback mode to eliminate switching losses. When the loop tends to force below 25-kHz frequencies, the NCP1339 skips cycles to contain the power delivery. To help build rugged converters, the controller features several key protective features: an internal brown-out, a non-dissipative Over Power Protection for a constant maximum output current regardless of the input voltage, a latched over voltage protection through a dedicated pin.
  • Features
  • Loss-free Adjustable Over Power Protection - Limits the peak current according to input line voltage
  • Latched / Autorecovery Timer-Based Overload Protection - Short circuit protection for improved reliability
  • Brown Out Protection - Protects against drops in input mains voltage
  • High voltage startup current source - Provides a quick and lossless power-on sequence
  • Active Input Filter Capacitor Discharge Circuitry - Eliminates the need for a X2 resistors
  • Latch input for OVP and OTP implementations - Simple implementation of required protection functions
  • Valley Switching Operation with Valley-Lockout - Improved efficiency with noise immunity
