TPS61040DBVR is a high-frequency boost converter dedicated for small to medium LCD bias supply and white LED backlight supplies.

TPS61040DBVR is ideal to generate output voltages up to 28 V from a dual-cell NiMH/NiCd or a single-cell Li-Ion battery. The TPS61040DBVR can also be used to generate standard 3.3-V or 5-V to 12-V power conversions.

TPS61040DBVR operates with a switching frequency up to 1 MHz. This frequency allows the use of small external components using ceramic as well as tantalum output capacitors. Together with the thin WSON package, the TPS61040DBVR gives a very small overall solution size.

TPS61040DBVR has an internal 400-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.
