Description

The TPS6240x device series are synchronous dual step-down DC-DC converters optimized for battery powered portable applications. They provide two independent output voltage rails powered by 1-cell Li-Ion or 3-cell NiMH/NiCD batteries. The devices are also suitable to operate from a standard 3.3V or 5V voltage rail.

With an input voltage range of 2.5V to 6V the TPS62400 is ideal to power portable applications like smart phones, PDAs and other portable equipment.

With the EasyScale™ serial interface the output voltages can be modified during operation. The fixed output voltage versions TPS62401, TPS62402, TPS62403 support one pin controlled simple Dynamic Voltage Scaling for low power processors.

The TPS6240x operates at 2.
