Read more 4 Mbps CAN transceiver with 60V fault protection February 19, 20154 Mbps CAN transceiver with ±60V fault protection LTC2875 is an exceptionally rugged, high voltage tolerant CAN (controller area network) transceiver designed to greatly reduce field failures without the need of costly external protection devices. Read more Spread Spectrum Frequency Modulation Reduces Automotive LED Driver EMI January 30, 2015Spread Spectrum Frequency Modulation Reduces Automotive LED Driver EMI The large number of electronics in an automobile must have reasonably low electromagnetic interference (EMI) in order to avoid disturbing the radio reception, GPS navigation tools and other forms of communication and broadcast. Switch mode regulators are commonly used in this environment and they have to be designed to mitigate their inherently noisy nature. Read more Configurable buck DC/DCs deliver 8 A from 2 to 4 independent outputs January 9, 2015Configurable buck DC/DCs deliver 8 A from 2 to 4 independent outputs LTC3371 is a highly integrated general-purpose power management solution for systems requiring multiple low voltage power supplies. The device features four synchronous buck converters, each powered from independent 2.25V to 5.5V inputs, and each configurable to share up to four of eight available 1A power stages.
