STR3A451 Datasheet Off-line Pwm Controllers

Manufacturer: Sanken

Overview: Off-Line PWM Controllers with Integrated Power MOSFET STR3A400 Series Data.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The STR3A400 series are power ICs 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.

The product achieves high cost-performance power supply systems with few external components.

Key Features

  • 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).
  • Current Mode Type PWM Control.
  • Soft Start Function.
  • Automatic Standby Function No Load Power Consumption < 15mW.
  • Operation Mode Normal Operation -----------------------------PWM Mode Light Load Operation ------------------------ Green-Mode Standby ---------------------------.
