The TPS61041DBVR is a low power DC to DC boost converter in 5 pin SOT-23 package. This high frequency boost converter is dedicated for small to medium LCD bias supply and white LED backlight supplies. The TPS61041 is ideal to generate output voltages up to 28V from dual cell NiMH/NiCd or a single cell Li-Ion battery. It can also be used to generate standard 3.3V or 5V to 12V power conversions. The TPS61041 operates with a switching frequency up to 1MHz. This frequency allows use of small external components using ceramic as well as tantalum output capacitors. The device has an internal 250mA switch current limit offering lower output voltage ripple and allows use of a smaller form factor inductor for lower power applications. The low quiescent current (typically 28μA) together with an optimized control scheme allows device operation at very high efficiencies over the entire load current range.
