36VIN with 60V Transient Protection, Dual Tracking 3.5A(IOUT), 2.25MHz

Linear Technology announces the H-grade version of the LT3692A, a monolithic, dual output step-down switching regulator that delivers up to 3.5A of continuous output current from each channel. It operates from a VIN range of 3V to 36V with transient protection to 60V, 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 250kHz to 2.25MHz, 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. The LT3692AHUH is packaged in a 32-lead 5mm x 5mm QFN, priced starting at $4.95 each for 1,000 piece quantities. LT3692AHFE is packaged in a thermally enhanced TSSOP-38 and is FMEA compliant, pricing starts at $5.37 each for 1,000 piece quantities. Both versions are available from stock.
