Equation 26 yields a value of 315 kΩ. The resulting falling UVLO threshold, can be calculated by Equation 27,

where EN falling threshold (VENL) is 0.99 V (typical).

VIN-UVLO-FALLING = VENL × (RENB + RENT) / RENB

8.2.2.13 PGOOD

A typical pullup resistor value is 10 kΩ to 100 kΩ from the PGOOD pin to a voltage no higher than 18 V. If it is

desired to pull up the PGOOD pin to a voltage higher than 18 V, a resistor can be added from the PGOOD pin to

ground to divide the voltage detected by the PGOOD pin to a value no higher than 18 V.

8.2.2.14 Synchronization

The LM76005 switching action can synchronize to an external clock from 200 kHz to 500 kHz. TI recommends

connecting an external clock to the SYNC pin with a 50-Ω to 100-Ω termination resistor. Ground the SYNC pin if

not used.
