The TPS62410 device 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
voltage rail.
With an input voltage range of 2.5V to 6V, the
TPS62410 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. It
therefore supports Dynamic Voltage Scaling for low
power DSP and processors.
The TPS62410 operates at 2.25MHz fixed switching
frequency and enter the Power Save Mode operation

applications the devices can be forced into fixed
frequency PWM mode by pulling the MODE/DATA
pin high. In the shutdown mode, the current
consumption is reduced to 1.2 μ A. The device allows
the use of small inductors and capacitors to achieve
a small solution size.
The TPS62410 is available in a 10-pin leadless
package (3 × 3mm QFN)
