Product details

The LTC3103EMSE#PBF: The 1.2 MHz fixed switching frequency keeps external inductor and capacitor values small, suiting space-constrained point-of-load designs. This improves efficiency at light loads and reduces BOM count in battery-powered or industrial rail-conversion stages.

Thermal and package integration

Housed in a 10-lead MSOP with exposed pad (10-MSOP-EP), the package measures 3.00 mm × 3.00 mm.

Frequently asked questions

What is the closest functional alternative to the LTC3103EMSE#PBF?

The LT8620IMSE#PBF is a 2 A, 2.2 MHz synchronous buck in the same MSOP-EP package, offering higher output current at a higher switching frequency. The ADP2380AREZ is a 4 A, 1.4 MHz option in a different package. Neither is a pin-compatible drop-in; a board layout review is required for substitution.
