The LT1615/LT1615-1 micropower step-up DC/DC converters deliver efficient power boosting in a compact 5-lead ThinSOT package with 1mm low profile, ideal for high-density designs. The LT1615 supports 350mA current limit and 1.2V to 15V input for higher power systems, generating outputs up to 34V via a 36V switch and 400ns low off-time for tiny inductors and capacitors. The LT1615-1 offers 100mA limit and 1V to 15V input for low-power single-cell applications. Operating from -40°C to 85°C, these converters ensure reliable performance in boost topologies without transformers.
