Description

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.

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 tiny SOT23 package, the TPS61040/41 gives a 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.
