Milpitas, Calif.Linear Technology announced the H-grade version of the LT3470, a 40-V micropower step-down DC/DC converter with integrated boost and catch diodes in a 2mm x 3mm DFN package.
It operates from input voltages of 4V to 40V, delivering up to 200mA of output current. The LT3470 is optimized for 2-cell Li-Ion, wall adapter or automotive power sources. Burst Mode operation reduces quiescent current to 26-µA, making it suitable for always-on automotive systems.
Additional applications include automotive battery regulation, power for portable products, distributed supply regulation, industrial supplies and wall transformer regulation.
The H-grade version operates up to a junction temperature of 150°C, compared to the E- and I-grade maximum junction temperature of 125°C. All electrical specifications are identical for the E-, I- and H-grade versions.
The H- grade parts are both tested and guaranteed to the maximum junction temperature of 150°C.
