FEATURES  
DESCRIPTION  
•
•
•
1.8-V to 6-V Input Voltage Range  
The TPS61040/41 is  
a
high-frequency boost  
converter 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 Soft Start  
The TPS61040/41 operates with  
a
switching  
frequency up to 1 MHz. This allows the use of small  
external components using ceramic as well as  
tantalum output capacitors. Together with the thin  
SON 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  
quiescent 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 SOT23-5 and 2 × 2 × 0.8-mm SON
