LOW POWER DC/DC BOOST CONVERTER IN SOT-23 PACKAGE  
FEATURES  
DESCRIPTION  
•
•
•
1.8 V to 6 V Input Voltage Range  
The TPS61040/41 is a high-frequency boost con-  
verter dedicated for small to medium LCD bias supply  
and white LED backlight supplies. The device is ideal  
to generate output voltages up to 28 V from a dual  
cell NiMH/NiCd or a single cell Li-Ion battery. The  
part can also be used to generate standard 3.3 V/5 V  
to 12 V power conversions.  
Adjustable Output Voltage Range up to 28 V  
400 mA (TPS61040) and 250 mA (TPS61041)  
Internal Switch Current

Up to 1 MHz Switching Frequency  
28 µA Typical No Load Quiescent Current  
1 µA Typical Shutdown Current  
Internal Softstart  
The TPS61040/41 operates with a switching fre-  
quency up to 1 MHz. This allows the use of small  
external components using ceramic as well as tanta-  
lum output capacitors. Together with the tiny SOT23  
package, the TPS61040/41 gives a very small overall  
solution size. The TPS61040 has an internal 400 mA  
switch current limit, while the TPS61041 has a 250  
mA switch current limit, offering lower output voltage  
ripple and allows the use of a smaller form factor  
inductor for lower power applications. The low quiesc-  
ent current (typically 28 µA) together with an  
optimized control scheme, allows device operation at  
very high efficiencies over the entire load current  
range.  
Available in a Tiny 5-Pin SOT23 Package
