Description

General part information

TPS62420 Series

The TPS6242x device is a synchronous dual step-down DC–DC converter. 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 3.3-V or 5-V voltage rail.

With an input voltage range of 2.5 V to 6 V, the TPS6242x is ideal for battery-powered portable applications like smart phones, PDAs, and other portable equipment.

With the EasyScale™ serial interface the output voltages can be modified during operation. It therefore supports dynamic voltage scaling for low power DSP and processors.
