MC44605 Datasheet | onsemi

features that make it particularly suitable for multisynchronized monitor applications. The MC44605 synchronization arrangement enables operation from 16 k Hz up to 130 k Hz. This product was optimized to operate with universal mains voltage, i.e., from 80 V to 280 V, and its high current totem pole output makes it ideally suited for driving a power MOSFET. The MC44605 protections enable a well- controlled and safe power management. Four major faults while detected, activate the analogic counter of a disabling block designed to perform a latched circuit output inhibition. Features http://onsemi.
