ZHCSKK3B December 2019 – February 2022 TPS6594-Q1
PRODUCTION DATA
The power resources provided by the TPS6594-Q1 device includes synchronous, current mode control bucks and linear LDOs. These supply resources provide power to the external processors, components, and modules inside the TPS6594-Q1 device. The supply of the bucks, the PVIN_Bx pins, must connect to the VCCA pin externally. The supply of the LDOs, the PVIN_LDOx pins, may connect to the VCCA pin or a buck output which is at a lower voltage level than the VCCA.
The voltage output of each power resource is continuously monitored by a dedicated analog monitor on an independent reference voltage domain. An unused regulator can also be used as a voltage monitor for an external rail by connecting the external rail to the FB_Bn the VOUT_LDOn pin. A residual voltage checking option is also available for each power resource to ensure the output voltage has dropped below 150 mV before it can be powered up again.
Table 8-1 lists the power resources provided by the TPS6594-Q1 device.
