Tunable Loop™ SLIN Series DC-DC Converters

Bel Fuse's line of non-isolated DC-DC converters


The Tunable Loop™ SLIN Series power modules from Bel Fuse are non-isolated, Point of Load (POL) DC-DC converters that deliver up to 50 A of output current in pick-and-placeable, surface-mount packages, ranging in size depending on output current capability. The modules operate over a wide 2.4 V to 14 V input voltage range and provide a precisely regulated output voltage from 0.6 V to 5.5 V. The output voltage can be programmed using an external resistor or external voltage source.

Features include input under-voltage lockout, remote on/off, adjustable output voltage, over-current and over-temperature protection, and UL, CSA and VDE recognition. All models are RoHS EU Directive 2022/95/EC compliant.
