STR3A475HDL - Off-line PWM Controllers

Description

The STR3A475HDL is power IC for switching power supplies, incorporating a MOSFET and a current mode PWM controller IC.

The low standby power is accomplished by the automatic switching between the PWM operation in normal operation and the burst-oscillation under light load conditions.

Features

  • Bare Lead Frame: Pb-free (RoHS Compliant).
  • Low Thermal Resistance Package.
  • Improving circuit efficiency (Since the step drive control can keep VRM of secondary rectification diodes low, the circuit efficiency can be improved by low VF).
  • Noise Reduction.
  • Current Mode Type PWM Control.
  • Soft Start Function.
  • Automatic Standby Function No Load Power Consumption.
