General Description

SD4871 is a current mode PWM controller IC for high performance, low standby power offline flyback converter application.

In no load or light load condition, the IC operates in Light Load Mode to reduce switching loss and improve efficiency.

Large startup resistor could be used in the startup circuit to minimize the standby current because of low startup current.

Key Features

  • Battery Chargers.
  • Frequency shuffling to improve EMI performance.
  • Adapters.
  • Light Load Mode for minimum standby power.
  • Set-Top Box Power Supplies.
  • External programmable switching frequency.
  • 3μA low startup current.
  • Internal LEB circuit.
  • VDD over voltage and under voltage protection.
  • Gate output maximum voltage clamp.
  • Current limiting.
  • Over load protection.
  • SOT-23-6L package.
