TPS6104x Switch Boost Converters

Texas Instruments offers its TPS6104x 28 V, 250 mA switch boost converter in SOT-23 for LCD and white LED applications

Image of Texas Instruments' TPS6104x Switch Boost ConvertersTexas Instruments' TPS6104x is a high-frequency boost converter dedicated for small to medium LCD bias supply and white LED backlight supplies. The device is ideal for generating 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 or 5 V to 12 V power conversions.

The TPS6104x 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 TPS6104x gives a very small overall solution size. The TPS61040 device has an internal 400 mA switch current limit, while the TPS61041 device 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. 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.

Features
  • 1.8 V to 6 V input voltage range
  • Adjustable output voltage range up to 28 V
  • 400 mA (TPS61040) and 250 mA (TPS61041) internal switch current
