NCP1203 Datasheet Pwm Current-mode Controller

Manufacturer: onsemi

Overview: NCP1203 PWM Current-Mode Controller for Universal Off-Line Supplies Featuring Standby and Short Circuit Protection Housed in SOIC−8 or PDIP−8 package, the NCP1203 represents a major leap toward ultra−compact Switchmode Power Supplies and represents an excellent candidate to replace the UC384X devices. Due to its proprietary SMARTMOS™ Very High Voltage Technology, the circuit allows the implementation of complete off−line AC−DC adapters, battery charger and a high−power SMPS with few external components.

Key Features

  • a high.
  • voltage startup FET which ensures a clean and loss.
  • less startup sequence. Its current.
  • mode control naturally provides good audio.
  • susceptibility and inherent pulse.
  • by.
  • pulse control. 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 improved efficiency at light loads while offering excellent performance in standby conditio.
