STR-Y6456 - Power IC

Download the STR-Y6456 datasheet PDF. This datasheet also covers the STR-Y6400 variant, as both devices belong to the same power ic family and are provided as variant models within a single manufacturer datasheet.

General Description

The STR-Y6400 series products are power ICs for quasi-resonant switching type power supplies, incorporating a power MOSFET and a controller IC.

Key Features

  • s TO-220F-7 Multi-Mode Control 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 load range. In Standby: Auto Standby (Auto Burst-Oscillation) Under Low to Middle Load Conditions: 1 or 2 Bottom-Skip Quasi-Resonant Operation (Bottom-Skip QR) Under Middle to Rating (or Heavy) Load Conditions: Quasi-Resonant Operation (QR) Current-Mode Control Bottom-Skip Function with Delay Time Settin.

STR-Y6400 Series Power IC for Quasi-Resonant Type Switching Power Supply with High Efficiency, Low Noise and Low Standby Power in Full Load Range ■ General Descriptions The STR-Y6400 series products are power ICs for quasi-resonant switching type power supplies, incorporating a power MOSFET and a controller IC. The product achieves high efficiency and low noise power supply systems across the full load range, by the low standby power, the quasi-resonant operation, the bottom-skip quasi-resonant operation, and the burst-oscillation. The STR-L6400 series products are the different package (SIP-10) versions.
