Allegro MicroSystems, Inc. Announces Off-Line Quasi-Resonant Switching Regulators
The STR-Y6700 series is comprised of a power MOSFET and a multi-functional monolithic integrated circuit (MIC) controller designed for controlling switch mode power supplies. The quasi-resonant mode of operation, coupled with the bottom-skip function, allows high efficiency and low noise at low to high operational levels, while burst oscillation mode ensures minimum power consumption at standby. In order to sustain low power consumption under low load and in standby mode, the controller has built-in startup and standby circuits.
The compact 7-pin full mold package (TO220F-7L) reduces board space by requiring a minimum of external components, thus simplifying circuit design. This IC, including various protection functions, is an excellent choice for standardized, compact power supplies.
