DC/DC convertor draws 100uA quiescent
The LT3437 H-grade DC/DC convertor is suitable for automotive and industrial applications which are subjected to high ambient temperatures.
Linear Technology has released the H-Grade version of the LT3437 step-down switching regulator The device operates from continuous inputs of 3.3V to 60V and withstands transients up to 80V, making it suitable for automotive and telecommunications applications
Its 500mA internal switch delivers up to 400mA of continuous output current at voltages as low as 1.25V.
Burst mode operation reduces no-load quiescent current to less than 100uA, maximising battery run-time for always on applications.
The H Grade version is tested and guaranteed to a junction temperature of 140C, compared to the E and I Grade versions, which are specified for 125C maximum junction temperature.
All electrical specifications are identical for the E, I and H-grade versions.
The LT3437 H-grade version is suitable for automotive and industrial applications which are subjected to high ambient temperatures. Request a free brochure from Linear Technology Corp ...
