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.
The LT3669/-2 feature rugged line drivers with adjustable slew rates and current limit which are externally adjustable to optimize EMC performance. The line drivers can source/sink up to 250mA of current each or 500mA when connected together, with a minimal residual voltage of less than 2.1V. An adaptive line driver pulsing scheme safely switches heavy loads. The drivers are easily configurable as push-pull, pull-up or pull-down to maximize system flexibility. Other features include current limit detection and thermal shutdown. The LT3669EUFD and LT3669EUFD-2 are both available from stock in a 28-Pin thermally enhanced 4mm x 5mm QFN package. 1,000 piece pricing starts at
$3.55 each. Industrial grade versions, the LT3669IUFD and LT3669IUFD-2, are guaranteed to operate over the -40°C to +125°C operating junction temperature range and the high temperature grade versions, the LT3669HUFD and LT3669HUFD-2 are guaranteed to operate over the -40°C to +150°C. All versions are available from stock. For more information, visit www.linear.com/product/LT3669.
