NCP1060: High-Voltage Switcher for low Power offline SMPS

  • The NCP1060 integrate a fixed frequency current mode controller with a 700 V MOSFET. Available in a PDIP−7 and SOIC-10 package, the NCP1060 offer a high level of integration, including soft−start, frequency−jittering, short−circuit protection, skip−cycle, adjustable peak current set point, ramp compensation, and a Dynamic Self−Supply (eliminating the need for an auxiliary winding).

    Unlike other monolithic solutions, the NCP1060 is quiet by nature: during nominal load operation, the part switches at one of the available frequencies (60 or 100 kHz). When the output power demand diminishes, the IC automatically enters frequency foldback mode and provides excellent efficiency at light loads. When the power demand reduces further, it enters into a skip mode to reduce the standby consumption down to a no load condition.

    Protection features include: a timer to detect an overload or a short−circuit event, Overvoltage Protection with auto−recovery and AC input line voltage detection (A version).

    The ON proprietary integrated Over Power Protection (OPP) lets you harness the maximum delivered power without affecting your standby performance simply via external resistors.

    The NCP1060/NCP1063 family can be seamlessly used both in non-isolated and in isolated topologies.
  • Features
  • Built−in 700 V MOSFET with RDS(on) of 34 Ω - Up to 8W output SMPS design capability
  • Large Creepage Distance Between High−voltage Pins - Safer and more robust design even with SMD packages
  • Adjustable Peak Current up to 250 mA - Increased design scalibility
  • Direct Feedback connection for non-isolated converter - Simpler and lower cost Buck or Buck-Boost designs
  • Internal and Adjustable Over Power Protection (OPP) Circuit - Non dissipative proprietary technique to self protect the load
  • Auto-Recovery Output Short Circuit Protection with Timer-Based Detection - Provides more robust protection without worrying about the coupling of the aux winding
  • Frequency Jittering (including during frequency foldback mode) - Better EMI Signature Over the Entire Operating Range
  • Current−Mode Fixed Frequency Operation – 60 or 100 kHz (130 kHz on demand) - Ability to scale for efficiency or size
  • Frequency Foldback Operation - Improved efficiency at light load / Improved EMI over the entire load conditions
  • With (A version) or without (B version) AC Input Voltage Line Detection - Enhanced Protection Against Faults when AC line is too low or for power supply with Vin down to 21 Vdc
