Power Integrations, AC-DC Converter 7-Pin, DIPB TOP249YN

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
