FEATURES  
DESCRIPTION  
•
Qualified for Automotive Applications  
•
Efficiency > 90% at Nominal Operating  
Conditions  
The TPS61240-Q1 device is  
a
high efficient  
synchronous step up DC-DC converter optimized for  
products powered by either a three-cell alkaline, NiCd  
or NiMH, or one-cell Li-Ion or Li-Polymer battery. The  
TPS6124x supports output currents up to 450mA.  
The TPS61240-Q1 has an input valley current limit of  
500mA.  
•

•
•
•
•
•
Total DC Output Voltage Accuracy 5.0V±2%  
Typical 30 mA Quiescent Current  
Best in Class Line and Load Transient  
Wide VIN Range From 2.3V to 5.5V  
Output current up to 450mA  
With an input voltage range of 2.3V to 5.5V the  
device supports batteries with extended voltage  
range and are ideal to power portable applications  
like mobile phones and other portable equipment.  
The TPS6124x boost converter is based on a  
quasi-constant on-time valley current mode control  
scheme.  
Automatic PFM/PWM Mode transition  
Low Ripple Power Save Mode for Improved  
Efficiency at Light Loads  
•
•
•
•
Internal Softstart, 250ms typical Start-Up time  
3.5MHz Typical Operating Frequency  
Load Disconnect During Shutdown  
The TPS6124x presents a high impedance at the  
VOUT pin when shut down. This allows for use in  
applications that require the regulated output bus to  
be driven by another supply while the TPS6124x is  
shut down.  
Current Overload and Thermal Shutdown  
Protection  
•
Three Surface-Mount External Components  
Required (One MLCC Inductor, Two Ceramic  
Capacitors)  
Total Solution Size <13 mm2  
During light loads the device will automatically pulse  
skip allowing maximum efficiency at lowest quiescent  
currents. In the shutdown mode, the current  
consumption is reduced to less than 1mA.  
•
•
Available in a 2×2-SON Package  
TPS6124x allows the use of small inductors and  
capacitors to achieve a small solution size. During  
shutdown, the load is completely disconnected from  
the battery. The TPS6124x is available in a 2×2 SON  
package.
