Step-down DC/DC converter targets load dump and cold-crank conditions
January 12, 2012 // Paul Buckley
Linear Technology has unveiled the H-grade version of the LT3692A, a monolithic, dual output step-down switching regulator that delivers up to 3.5 A of continuous output current from each channel. The device operates from a V IN range of 3 V to 36 V with transient protection to 60 V, making it ideal for load dump and cold-crank conditions found in automotive applications.
Independent input, shutdown, feedback, soft-start, current limit and comparator pins for each channel simplify complex power supply tracking/sequencing requirements. The LT3692A's switching frequency is user-programmable from 250 kHz to 2.25 MHz, enabling the designer to optimize efficiency while avoiding critical noise-sensitive frequency bands.
The H-grade versions operate up to a junction temperature of 150°C, compared to the E- and I-grade versions' 125°C maximum junction temperature. All electrical specifications are identical for the E, I and H. The H-grade parts are tested and guaranteed to the maximum junction temperature of 150°C, and are ideal for automotive and industrial applications which are subject to high ambient temperatures.
