Buck Controller – input voltage range from 1.8V to 25V

Semtech announced the SC1486A , a dual synchronous DDR and DDR2 buck power supply controller, targeting notebooks, tablet PCs, and embedded applications. The SC1486A builds upon the widely accepted Semtech SC1486 DDR power supply controller.

The upgraded version provides a power supply solution for systems designers that are specifying DDR2 memory, or who want to design a migration path to DDR2 memory with minimal board changes. The SC 1486A is pin compatible with its predecessor allowing for seamless transition. The SC 1486A offers designers a wide input voltage range from 1.8V to 25V, enabling the device to directly interface with standard battery configurations and a/c adapters.

Also provided are two independently programmable output voltages that can be adjusted from 5.5V down to 0.5V.
