NOTE
Information in the following Applications section is not part of the TI component specification,
and TI does not warrant its accuracy or completeness. TI's customers are responsible for
determining suitability of components for their purposes. Customers should validate and test
their design implementation to confirm system functionality.
6.1 Application Information
The TPS65154 devices is intended primarily for use in notebook PC and tablet applications. It needs
these two supply voltages
• A regulated 3.3-V or 5-V supply for the LCD bias functions
• A direct connection to the battery for the WLED driver functions
The device configuration parameters are set by I²C interface and stored in the on-chip nonvolatile
memory.
6.2 Typical Application
Figure 6-1 shows the recommended application circuit for typical applications. The I²C interface is used to
optimize the circuit's operating parameters for a specific application. If different component values are
used, make sure that the values are within the recommended operating conditions (see Recommended
Operating Conditions). If different component values are used, the compensation components may also
need to be optimized for stability and best performance.
