Figure 52. LTM8060F Simplified Block Diagram

The LTM8060F contains power good comparators that trip when the FBn pin is at about ±8% of its regulated value.

The PGn output is an open-drain transistor that is off when the output is in regulation, allowing an external resistor

to pull the PGn pin high.

The LTM8060F is equipped with a thermal shutdown that inhibits power switching at high junction temperatures.

The activation threshold of this function is above the maximum temperature rating to avoid interfering with normal

operation, so prolonged or repetitive operation under a condition in which the thermal shutdown activates may

damage or impair the reliability of the device.
