TPS5516xQ1-EVM Evaluation Module for 1-A Single-Inductor Buck-Boost-
Converter
Figure 19. Spread Spectrum Enable Jumper Configuration
Default: Jumper Installed, Spread Spectrum Disabled

PG_DLY
The PG_DLY jumper sets the power-good delay time. This time defines how long before the power-good
pin (PG pin, TP3) goes low after the output voltage decreases to less than the PG undervoltage threshold
(PGTH_UV). The default of this jumper is 3ms (no jumper installed).
Figure 20. Power-Good Delay Selection Jumper Configuration
Default: Jumper Not Installed, 3-ms Delay
3.2.5
PS
The PS jumper selects between low-power mode (LPM) and pulse-width modulation (PWM). The default
of this jumper is PWM.
Figure 21. Low-Power-Mode Enable Jumper Configuration
Default: Jumper Set to PWM, LPM Prohibited
3.2.6
Vout_Set
The Vout_Set jumper selects the output voltage for the TPS5516x-Q1 device. For the TPS55165-Q1
device, the default of this jumper is 5V. Move this jumper to 12V select the 12-V output voltage. If no
jumper is installed, the output voltage defaults to 5 V.
NOTE:
To make a jumper change effective, power cycle the supply or turn off the output (move the
IGN jumper to OFF while the device is unlatched).
