junction temperature TJ (°C) can be deducted from the
following relation:
Where VTJ is the voltage at VTJ pin in volts.
Power Good and Power On Reset
During power up the output regulator will be disabled
until VIN reaches a value of approximately 4V. About
500mV hysteresis is present to eliminate noise-induced
oscillations.
Under-voltage and over-voltage conditions on the regu-
lator output are detected through an internal window
comparator. A logic high on the PG output indicates that
the regulated output voltage is within about +10% of the
nominal selected output voltage.
Power Tracking
The power tracking pins STP and STN are the inputs to
a comparator, whose HI output forces the PWM control-
ler to skip switching cycle.
1. Linear Tracking
In this application, it is always the case that the lower
voltage supply VC tracks the higher output supply VP.
