STR-X6750F

AC DC Converters, Offline Switchers Overview

The STR-X6750F is a power IC for quasi-resonant type switching power supplies, incorporating a power MOSFET and a controller IC. It achieves high efficiency and low noise across the full load range via multi-mode control. The device operates in three steps: UVLO intermittent oscillation or auto burst-oscillation under standby conditions, bottom-skip quasi-resonant operation under low to middle loads, and standard quasi-resonant operation under middle to heavy loads.

AC DC Converters, Offline Switchers Feature Summary
