This document introduces the LTC3631, LTC3632 and LTC3642 three switching power supply products, which are packaged in 3mm x 3mm DFN. They can operate with a wide input voltage range and withstand 60V of instantaneous voltage surges.
This document introduces the LTC3631, LTC3632, and LTC3642 as robust, monolithic DC/DC step-down solutions designed for industrial and test equipment. These devices produce a well-regulated supply even in volatile voltage environments by sustaining repetitive 60V surges on input rails ranging from 9V to 24V.
The device can sustain repetitive surges of up to 60V.
The LTC3642 uses an internal timer that lasts for 0.75ms.
