MILPITAS, CA - June 30, 2014 - The LT3669 is an IO-Link PHY compatible (COM1/COM2/COM3) industrial transceiver that includes a high efficiency step-down regulator and a low dropout linear regulator. The device offers cable interface protection to ±60V. Wake-up detect functionality as well as a programmable power-on reset timer are included for system reliability. The LT3669/-2 operates from a 7.5V to 40V input voltage range, making it ideal for industrial sensor applications. The LT3669’s internal switching regulator can deliver up to 100mA of load current, whereas the LT3669-2 delivers up to 300mA. Both versions can deliver high efficiency at output voltages from 0.8V to 16V. The integrated LDO, powered from the switcher output, provides an additional output to offer additional design flexibility while maintaining high efficiency. Both versions feature constant frequency/synchronizable operation with programmable switching frequencies between 250kHz and 2.2MHz. This enables the use of tiny externals, which combined with the 4mm x 5mm QFN-28, offer a highly compact solution footprint for industrial IO-Link sensor applications.
