AC/DC Converter IC
The LinkSwitch is a highly integrated high-voltage power conversion IC designed to displace low power linear transformers. The device is available in through-hole and surface mount DIP packages. The LNK501 combines a 700-volt power MOSFET, PWM controller, high voltage start-up, current limit, and thermal shutdown circuitry onto a single CMOS chip. Applications include linear transformer replacement in adapters and battery chargers for a wide range of personal electronics.
