APPLICATION INFORMATION
DSP power application
In DSP power applications, TPS56302 is used in the applications that require more current for peripheral and
DSP I/O. The power good (PG) output can be used for monitoring or controlling as an optional function. In the
EVM schematic, Q3, D1, R1, and R2 are the circuit to show this function.

Figure 32. TPS56302 For High Peripheral Current DSP Application
TPS56300 is used in the applications that require high current for core, but low current for I/O. Another important
feature is that, if the input voltage is the same as the LDO output, the LDO switch acts as a distribution switch
to control the on/off of the LDO output.
