APPLICATION INFORMATION
evaluation module
In many DSP applications, the voltage bus powering DSP I/O also has to power peripheral circuitry. The total
current is much higher than the requirement for the I/O only. This is the reason to use the high-efficiency ripple
regulator to power I/O. In turn, the core power is delivered by LDO output. Since the I/O voltage is lower than
the input voltage in cases such as 5-V input, but higher than the core voltage, the ripple regulator output should
be used as the input voltage for LDO to achieve higher efficiency. In EVM testing, J1
4 (RR
OUT) is connected
to J2
1(VI
LDO). The test results displayed in this section are all based on this configuration.

When an output current greater than 4 A is desired on the ripple regulator, please add a 10
resistor (R17) between pin 18 and Q1:A.
Because the EVM is configured for 4 A and below, R17 is 0
and is not included on the module.
