TPS61041DBVR Description
The TPS61041DBVR is a high-frequency boost converter designed for LCD bias and white LED backlight sources in small to medium sizes. A dual-cell NiMH/NiCd or a single-cell Li-Ion battery can be used to generate output voltages up to 28 V using this device. Standard 3.3-V or 5-V to 12-V power conversions are also possible with this component.
The switching frequency of the TPS61041DBVR is up to 1 MHz. Small external components, such as ceramic and tantalum output capacitors, can be used at this frequency.
