Step-down convertor takes diodes onboard
The LT3470 is a 40V micropower step-down DC/DC convertor with integrated boost and catch diodes in a ThinSOT package.
The LT3470 is optimised for two-cell Li-ion, wall adapter or automotive power sources.
Burst Mode operation reduces quiescent current to only 26uA, making it ideal for applications such as always-on automotive systems.
The entire solution footprint is only 50mm2, making it ideal for space constrained applications.
The H-grade version of the LT3470 operates up to a junction temperature of +150C, compared with the E- and I-grade maximum junction temperature of +125C.
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 150degC.
They are well suited for automotive and industrial applications, which are subjected to high ambient temperatures.
The LT3470HDDB is available from stock in a 2 x 3mm DFN-8 package.
Pricing starts at US $3.07 each for 1000-piece quantities. Request a free brochure from Linear Technology Corp ...
