Description
LT3990IMSE#TRPBF 62 V 350 mA Step-Down Regulator
The LT3990IMSE#TRPBF is an adjustable 62 V, 350 mA step-down regulator with integrated boost and catch diodes. Its 2.5 µA quiescent current, 4.2 V to 62 V operating range and 200 kHz to 2.2 MHz switching-frequency range suit always-on industrial and automotive rails.
What LT3990IMSE#TRPBF Is Designed to Do
The LT3990IMSE#TRPBF is an adjustable 62 V, 350 mA step-down regulator with integrated boost and catch diodes. Its 2.5 µA quiescent current, 4.2 V to 62 V operating range and 200 kHz to 2.2 MHz switching-frequency range suit always-on industrial and automotive rails. Final suitability depends on the complete circuit, software, thermal, mechanical, qualification and lifecycle requirements.
For sourcing, the base family name is not enough. The full LT3990IMSE#TRPBF ordering code, package, packing format, revision or grade, source condition and required inspection evidence should be confirmed against the actual order.
