Buck regulator offers 60-V transient protection

Buck regulator offers 60-V transient protection

The H-grade version of the LT3692A is a dual output step-down switching regulator that delivers up to 3.5-A continuous output current from each channel. It operates from 3 to 36 V with transient protection to 60 V. It suits load dump and cold-crank conditions found in automotive applications.

The step-down regulator features shutdown, feedback, soft-start, current limit and comparator pins for each channel to simplify complex power supply tracking/ sequencing requirements. The switching frequency is user-programmable from 250 kHz to 2.25 MHz. The H-grade versions operate up to a junction temperature of 150°C, compared to the E- and I-grade 125˚C maximum junction temperature. (Ea/1,000: LT3692AHUH, $4.95; LT3692AHFE, $5.37 — available now.)
