They are designed for ease of use, low external ponent count, and spaceconscious power systems. These devices feature accurate 1%, 0.6-V reference, and integrated boost switch. A sample of petitive features include: 1.5-V to 22-V wide conversion input voltage range, very low external ponent count, DCAP™ mode control for super fast transient, auto-skip mode operation, internal soft-start control, selectable frequency, and no need for pensation. The conversion input voltage ranges from 1.5 V to 22 V, the supply voltage range is from 4.5 V to 25 V, and the output voltage range is from 0.6 V to 5.5 V. These devices are available in 5 mm x 6 mm, 22-pin QFN package and is specified from - 40°C to 85°C. Device Information (1) PART...
