TinySwitch-LT Series AC / DC Off Line Converters:

TinySwitch-LT incorporates a 650 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
• 650 V rated integrated MOSFET
• Selectable current limit through BP/M capacitor value
• Higher current limit extends peak power or, in open frame applications, maximum continuous power
• Tight I2f parameter tolerance reduces system cost
• On-time extension—extends low line regulation range/hold-up time to reduce input bulk capacitance
• Frequency jittering reduces EMI filter costs
• Output overvoltage shutdown with optional Zener
• Pin-out simplifies heat sinking to the PCB
• Applications: Appliances & Unstablee main Voltage, IOT & Smart home, Ultra-low standby power
