using the TPS5210 when both 12 V and 5 V are available
When both 12 V and 5 V are available, several components can be removed from the basic schematic shown
above. R1, R4, and C9 are no longer required if 5 V is brought in directly to INHIBIT and LODRV. However, if
undervoltage lockout for the 5-V input is desired, R1 and R4 can be used to set the startup setpoint. The INHIBIT
pin trip level is 2.1 V. Select R4:

Figure 21. 5-V Input with UVLO
using the TPS5210 when only 5 V is available
The TPS5210 controller requires 12 V for internal control of the device. If an external source for 12 V is not
available, a small on-board source must be included in the design. Total 12-V current is very small, typically
about 20 mA, so even a small charge pump can be used to generate the supply voltage. The power stage is
not voltage dependent, but component values must be selected for 5-V inputs and the frequency of operation
is dependent upon the power stage input voltage.
