STR-Y6456 - Power IC for Quasi-Resonant Type Switching Power Supply

Description

The STR-Y6456 is power IC for quasi-resonant switching type power supplies, incorporating a power MOSFET and a controller IC.

Features

  • Multi operation mode The operation mode switching with four steps according to load conditions achieves the optimal high efficiency and low noise power supply systems across the full range of loads.
  • Current mode control method.
  • The built-in startup circuit reduces the power consumption.
  • Auto burst oscillation operation reduces dissipation. Input power PIN ≤ 0.1W at no load.
  • Standby input compensation.
  • Overcurrent protection with AC input compensation function.

Power IC for Quasi-Resonant Type Switching Power Supply with High Efficiency, Low Noise and Low Standby Power in Full Load Range STR-Y6456 Sep, 2013 ◆General Descriptions The STR-Y6456 is power IC for quasi-resonant switching type power supplies, incorporating a power MOSFET and a controller IC. The product is automatically switched to the quasi resonant operation, one bottom skip quasi resonant operation and two bottom skip operation in normal operation, and to the burst oscillation operation in light load. That realizes the low standby power and a power supply system with high cost performance, low external part count can be easily composed.
