High Efficiency—Up to 95%
VIN Range From 2.5 V to 6 V
The TPS6240x device series are synchronous dual
step-down DC-DC converters optimized for battery
2.25 MHz Fixed Frequency Operation
powered portable applications. They provide two
Output Current 400 mA and 600 mA
independent output voltage rails powered by 1-cell
Adjustable Output Voltage From 0.6V to VIN
Li-Ion or 3-cell NiMH/NiCD batteries. The devices are
also suitable to operate from a standard 3.3V or 5V
Pin Selectable Output Voltage Supports
voltage rail.
Simple Dynamic Voltage Scaling
With an input voltage range of 2.5V to 6V the
EasyScale Optional One-Pin Serial Interface
TPS62400 is ideal to power portable applications like
Power Save Mode at Light Load Currents
smart phones, PDAs and other portable equipment.
