DC-DC converters are commonly used to transfer energy from one part of an electrical system to another. The LT8067IY is an isolated, adjustable step down DC DC converter specifically designed for use in automotive, industrial and communications applications. This device is capable of providing a continuous input voltage range of 9V to 36V and outputs a selectable voltage range of 1.8V to 5.2V.

The LT8067IY has an integrated non-synchronous buck converter that offers a wide output voltage range and high peak efficiency of up to 94%. The device has a very low noise profile and extended temperature range of -40°C to +125°C. It is also RoHS and REACH compliant.

The primary advantage of the LT8067IY is its exceptional tolerance to input voltage transients arising from input capacitance changes and supply voltage variation. This ability makes it ideal for automotive, industrial and communications applications. The device is also extremely robust, with integrated short-circuit and over-temperature protection.

The size of the LT8067IY is smaller than typical devices in its class, at only 9.89mm x 10.92mm x 3.2mm. This small size makes the device suitable for a range of applications in different form factors. It is also designed for a very low output noise profile.

The LT8067IY control scheme is based on a feedback system. This system monitors the output voltage and adjusts the switching element, the MOSFET, to regulate the output voltage. The device also includes a bootstrap circuit to drive the high side MOSFET during a portion of the operation cycle. This ensures that the output voltage remains stable over a wide input voltage range, even in the presence of significant input voltage variation.

The device features a wide range of protection features, such as input reverse voltage protection, thermal limiting, output current limiting, output short-circuit protection, and output overvoltage protection. This provides an added measure of safety and failsafe protection for the device and the system it is installed in.

The device also features programmable soft-start, designed to limit inrush current at turn on. This ensures that the device supply is well protected from overloading, which could otherwise lead to an emergency shutdown.

Overall, the LT8067IY is an isolated, adjustable step down DC DC converter specifically designed for use in automotive, industrial and communications applications. This device can provide a continuous input voltage range of 9V to 36V and outputs a selectable voltage range of 1.8V to 5.2V. It features a wide range of protection features, as well as an integrated non-synchronous buck converter, making it an ideal solution for a variety of applications.
