Overview

Product Highlight

  • Topology: Flyback
  • Input Voltage: 8.5 to 10 V
  • Output Current-Max: 350 mA
  • Switching Frequency-Max: 143 kHz

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).

Unlike other monolithic solutions, the NCP101X is quiet by nature: during nominal load operation, the part switches at one of the available frequencies (65 − 100 − 130 kHz). When the current setpoint falls below a given value, e.g. the output power demand diminishes, the IC automatically enters the so−called skip−cycle mode and provides excellent efficiency at light loads. Because this occurs at typically 1/4 of the maximum peak value, no acoustic noise takes place. As a result, standby power is reduced to the minimum without acoustic noise generation.

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

Applications:

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