$Features & Applications

The NCP101X series integrates a fixed−frequency current−mode controller and a 700 V MOSFET. Housed in a PDIP−7, PDIP−7 Gull Wing, or SOT−223 package, the NCP101X offers everything needed to build a rugged and low−cost power supply, including soft−start, frequency jittering, short−circuit protection, skip−cycle, a maximum peak current setpoint and a Dynamic Self−Supply (no need for an auxiliary winding).

For improved standby performance, the connection of an auxiliary winding stops the DSS operation and helps to consume less than 100 mW at high line. In this mode, a built−in latched overvoltage protection prevents from lethal voltage runaways in case the Optocoupler would brake. These devices are available in economical 8−pin dual−in−line and 4−pin SOT−223 packages.

Key Features:

  • Built−in 700 V MOSFET with Typical RDSon of 11 Ω and 22 Ω
  • Large Creepage Distance Between High−Voltage Pins
  • Current−Mode Fixed Frequency Operation: 65 kHz – 100 kHz − 130 kHz
  • Skip−Cycle Operation at Low Peak Currents Only: No Acoustic Noise!
  • Dynamic Self−Supply, No Need for an Auxiliary Winding
  • Internal 1.0 ms Soft−Start
  • Latched Overvoltage Protection with Auxiliary Winding Operation
  • Frequency Jittering for Better EMI Signature
  • Auto−Recovery Internal Output Short−Circuit Protection
  • Below 100 mW Standby Power if Auxiliary Winding is Used
  • Internal Temperature Shutdown
  • Direct Optocoupler Connection
  • SPICE Models Available for TRANsient Analysis
  • These are Pb−Free and Halide−Free Devices


  • Low Power AC/DC Adapters for Chargers
  • Auxiliary Power Supplies (USB, Appliances,TVs, etc.)
