TOP246Y [Power Integrations]

TOPSwitch-GX uses the same proven topology as TOPSwitch, cost effectively integrating the high voltage power MOSFET, PWM control, fault protection and other control circuitry onto a single CMOS chip. Many new functions are integrated to reduce system cost and improve design flexibility, performance and energy efficiency. The family features extended power range, no heatsink required up to 34 W using P/G packages, fully integrated soft-start, externally programmable current limit, wider duty cycle, line sensing (UV/OV), line feed-forward, frequency jittering, and hysteretic thermal shutdown. EcoSmart technology provides extremely low consumption in remote off mode, frequency lowering with load for high standby efficiency, and allows shutdown/wake-up via LAN/input port.
