Product Summary
The TPS62410DRCR 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 TPS62410DRCR is also suitable to operate from a standard 3.3V or 5V voltage rail. It operates at 2.25MHz fixed switching frequency and enter the Power Save Mode operation at light load currents to maintain high efficiency over the entire load current range. The applications of the TPS62410DRCR include: Cell Phones, Smart-phones, PDAs, Pocket PCs, OMAP and Low Power DSP Supply, Portable Media Players, Digital Radio, Digital Cameras.
