The LT3973IMSE#PBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 4.2V to 42V and delivers up to 750mA output current. The device features an adjustable switching frequency from 195kHz to 2.15MHz, allowing optimization for efficiency or component size. It maintains a low quiescent current of 2.5µA during operation and drops to 1.9µA in shutdown mode. The IC is housed in a 10-lead MSOP package with exposed pad and supports a junction temperature range of -40°C to +125°C.
Verify the specific suffix matches the required package and temperature grade. Confirm RoHS compliance status through official documentation. Ensure ordering codes align with exact pinout and thermal requirements. Cross-reference datasheet revisions for any functional updates before finalizing procurement specifications.
Select this component when wide input voltage tolerance and low static current are critical. The adjustable frequency feature enables design flexibility for space-constrained layouts. Evaluate thermal performance requirements given the MSOP package constraints. Compare against fixed-frequency alternatives if cost sensitivity outweighs efficiency needs.
This part belongs to the LT3973 family of high-voltage buck regulators designed for demanding environments. The IMSE variant specifies industrial temperature rating and MSOP packaging. It complements other PMIC solutions requiring robust input voltage handling without sacrificing efficiency.
