TinySwitch-III Series AC - DC Преобразователи:

TinySwitch-III incorporates a 700 V power MOSFET, oscillator, high-voltage switched current source, current limit (user selectable) and thermal shutdown circuitry. The IC family uses an ON/OFF control scheme and offers a design flexible solution with a low system cost and extended power capability.

• Simple ON/OFF control, no loop compensation needed
• Selectable current limit through BP/M capacitor value
• Tight I2f parameter tolerance reduces system cost
• On-time extension—extends low line regulation range/hold-up time to reduce input bulk capacitance
• Pin-out simplifies heatsinking to the PCB
• Frequency jittering reduces EMI filter costs
• Self-biased: no bias winding or bias components
• hysteretic thermal shutdown protection with automatic recovery eliminates need for manual reset
• Improved auto-restart delivers <3% of="" maximum="" power="" in="" short-circuit="" and="" open="" loop="" fault="" conditions<=""/>
• Applications:Appliances,Audio & video, Meters & Industrial, Notebook adapters, TVs & Monitors
