7 Power Supply Recommendations

The TPS65154 device is designed to operate with two input supplies:

  • One supply in the range 2 V to 5.5 V powers the LCD bias functions. Typically, this is a regulated 3.3-V or 5-V supply generated by a dc-dc converter somewhere else in the system. Note that this supply must be higher than 2.5 V if the user wants to program the EEPROM.
  • One supply in the range 4.5 V to 24 V powers the WLED driver boost converter. Typically, this is an unregulated supply taken from the battery system in a notebook PC or tablet.

The input supplies must be stable and free of noise to achieve the full performance of the device. If the input supplies are located more than a few centimeters away from the TPS65154 device, additional bulk capacitance may be required. The input capacitance shown in Figure 6-1 is sufficient for typical applications.
