STR-W6700 ■ General
s Series Power IC for Quasi-Resonant Type Switching Power Supply with High Efficiency and Low Noise in Full Load Range The STR-W6700 series products are power ICs for quasi-resonant type switching power supplies, incorporating a power MOSFET and a controller IC, The product achieves high efficiency and low noise power supply systems by the quasi-resonant operation and the bottom-skip quasi-resonant operation. The STR-X6700 series products are the different package (TO-3PF) versions. ■ Features Multi-Mode Control The operation mode switching with three steps according to load conditions achieves the TO-220F-6 optimal high efficiency and low noise power supply systems across the full load range. (The confirmation of product number is necessary because some functions are different in each product.) ・In Standby (Under Standby Load Conditions): －UVLO Intermittent Oscillation by lowering output voltage — Switched by Standby Sign [ … ]
