Description for the TPS61041

The TPS6104x is a high-frequency boost converter dedicated for small to medium LCD biassupply and white LED backlight supplies. The device is ideal to generate output voltages up to 28 Vfrom a dual-cell NiMH/NiCd or a single-cell Li-Ion battery. The part can also be used to generatestandard 3.3-V or 5-V to 12-V power conversions.

The TPS6104x operates with a switching frequency up to 1 MHz. This frequency allows theuse of small external components using ceramic as well as tantalum output capacitors. Together withthe thin WSON package, the TPS6104x gives a very small overall solution size. The TPS61040 devicehas an internal 400-mA switch current limit, while the TPS61041 device has a 250-mA switch currentlimit, offering lower output voltage ripple and allows the use of a smaller form factor inductorfor lower power applications. The low quiescent current (typically 28 µA) together with anoptimized control scheme, allows device operation at very high efficiencies over the entire loadcurrent range.
