STR-Y6753 and STR-Y6754 Off-Line Quasi-Resonant Switching Regulators Features and Benefits - TO- 220F- 7L package - Lead (Pb) free pliance - The built-in startup circuit reduces the number of external ponents and lowers standby power consumption - Multi-mode control allows high efficiency operation across the full range of loads - Auto burst oscillation mode for standby mode, for improving low standby power at no load: input power < 30 m W at 100 VAC and < 50 m W at 230 VAC - Bottom-skip mode minimizes switching loss at medium to low loads - Internal MOSFET VDSS(min) is 650 V - Internal MOSFET RDS(on)(max) 1.9 Ω (STR-Y6753) or 1.4 Ω (STR-Y6754) - Built-in soft start function reduces stress applied to the incorporated power MOSFET and peripheral ponents - Step-on burst oscillation minimizes transformer audible noise - Built-in leading edge blanking (LEB) function eliminates Continued on the next page… Description The STR-Y6753 and STR-Y6754 each prise 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 ef ficiency 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. This enables output power for the STR-Y6753 up to 60 W with universal input or 100 W with a 380 VDC input, and for the STR-Y6754 up to 67 W with universal input or 120 W with a 380 VDC input. The pact 7-pin full mold package (TO220F-7L) reduces board space by requiring a minimum of external ponents, thus simplifying circuit design. This IC, including various protection functions, is an excellent choice for standardized, pact power supplies. Package: 7-Pin TO-220F Not to scale Typical Application T1 VAC C1 P...
