SLVS737–FEBRUARY 2007  
2.25MHz 2x800mA Dual Step Down Converter In Small 3x3mm QFN Package  
FEATURES  
DESCRIPTION  
•
•
•
•
•
•
High Efficiency—up to 95%  
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.  
VIN Range From 2.5 V to 6 V  
2.25 MHz Fixed Frequency Operation  
Output Current 2 x 800mA  
Adjustable Output Voltage From 0.6 V to VIN  
EasyScale™ Optional One Pin Serial Interface  
for Dynamic Output Voltage Adjustment  
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.  
•
•
•
•
Power Save Mode at Light Load Currents  
180° Out of Phase Operation  
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.  
Output Voltage Accuracy in PWM Mode ±1%  
Typical 32 µA Quiescent Current for both  
Converters  
•
•
100% Duty Cycle for Lowest Dropout  
The TPS62410 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. For low noise  
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 1.2µA. The device allows  
the use of small inductors and capacitors to achieve  
a small solution size.  
Available in a 10-Pin QFN (3×3mm)
