Linear Technology Corporation (Linear Technology CorporaTIon) Release version LT3692A H level, the device is a monolithic, dual output step-down switching regulator, each channel provides up to 3.5A continuous output current. LT3692A operates within a VIN range of 3V to 36V transient protection up to 60V, making it ideal for applications in automotive load dump and cold-crank conditions. Each separate input channel, shutdown, feedback, soft-start, current limit and comparator pins simplify complex power supply tracking / sequencing requirements. LT3692A switching frequency is user programmable from 250kHz to 2.25MHz, enabling the designer to optimize efficiency while avoiding critical noise-sensitive frequency bands.
H-grade version capable of up to 150? C to work thermostat, in contrast, E and I grade versions of the maximum junction temperature is 125? C. All electrical specifications of E, I and H-class versions are the same. H-grade parts are tested up to 150? C maximum junction temperature is guaranteed, ideal for automotive and industrial applications, such applications are at high ambient temperatures.
