Synchronous Inductive Converter supports USB interfaces.March 28, 2008 -
Series SP6669 delivers up to 600 mA and has output voltage that can be set as low as 0.6 or 1.5 V and 1.8 V for fixed output versions, which can be achieved from any input voltages from 2.5-5.5 V. Device operates at fixed internal switching frequency of 1.5 MHz and -40 to +85°C. Offering 0.4%/V and 0.5% of line and load regulations, it is offered in small form factor that eliminates discrete components giving system architects flexibility for developing space constrained solutions.
