Product Summary
The TPS62420DRCR is a synchronous dual step-down DC-DC converter optimized for battery powered portable applications. It provides two independent output voltage rails powered by 1-cell Li-Ion or 3-cell NiMH/NiCD batteries. The device is also suitable to operate from a standard 3.3V or 5V. The applications of the TPS62420DRCR include Cell Phones, Smart-phones, PDAs, Pocket PCs, OMAP and Low Power DSP Supply, Portable Media Players, Digital Radio and Digital Cameras.
