Power Integrations, AC-DC Converter 7-Pin, DIPB TOP244PN

TOPSwitch-GX integrates 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.High Design Flexibility Extended power range for higher power applications No heatsink required up to 34 W using P/G packages Fully integrated soft-start for minimum stress/overshoot Externally programmable accurate current limit Wider duty cycle for more power, smaller input capacitor Line under-voltage (UV) detection: no turn off glitches Line overvoltage (OV) shutdown extends line surge limit Regulates to zero load without dummy loading EcoSmart – Energy Efficient Allows shutdown/wake-up via LAN/input port
