October 2001 FS6M07652RTC for LCD Monitor SMPS Power Switch Product Brief Various Protection Features -- includes OLP, OVP, OCP & TSD Burst Mode Operation -- Lower Consumption in Standby Mode Features General Description The FS6M07652RTC is a highly integrated off-line power switch (FPS) specifically targeted for the LCD monitor fly-back power supply applications. This offers Burst Mode Operation for Standby mode to minimize power consumption by reducing switching loss. The FS6M07652RTC minimizes external components, simplifies design and lower cost by integrating a current sensing MOSFET and a PWM controller with a fixed operating frequency of 70kHz. The FS6M07652RTC provides internal protection including over voltage protection, over load protection, thermal shutdown protection and over current protection. The internal current sensing high voltage MOSFET offers a 650V min. breakdown rating. The FS6M07652RTC is available in the space-saving TO-220-5L package.
