Power Integrations, AC/DC Converter, 12V 7-Pin, DIP-B 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
