LinkSwitch-LP Series AC / DC Off Line Converters:

LinkSwitch-LP switcher ICs cost effectively replace all unregulated isolated linear transformer based (50/60Hz) power supplies up to 3 W output power. For worldwide operation, a single universal input design replaces multiple linear transformer based designs. The self-biased circuit achieves an extremely low no-load consumption of under 150 mW.

• Superior Performance over Linear and RCC
• Lowest component count switcher
• Hysteretic thermal shutdown protection
• Frequency jittering greatly reduces EMI ? enables low cost input filter configuration
• Proprietary E-Shield transformer eliminates Y capacitor
• Universal input range allows worldwide operation
• No-load consumption <150 mW="" at="" 265="" VAC="" input<=""/>
• Auto-restart reduces delivered power by >85% during short circuit and open loop fault conditions
• Simple ON/OFF control, no loop compensation needed
• Applications: Chargers for cell/cordless phones, MP3/portable audio devices
