LT1103CT7 Description

Short technical summary and product information.

The LT1103CT7 is an offline switching controller from Analog Devices designed for AC-DC converter applications. It supports flyback and forward topologies with output isolation. The device operates from an input voltage range of 7V to 30V and can deliver up to 100W of output power. Switching frequency is up to 200kHz. The controller features line and load regulation of ±1% without the need for an optocoupler. It includes fault protection with current limiting, overload, and overvoltage protection. The start-up current is only 200mA. The device is housed in a TO-220-7 package with formed leads for through-hole mounting. The operating temperature range is 0°C to 70°C. The duty cycle is 65%.
