Monolithic 4 Amp DC:DC Step-down Regulator

junction temperature TJ (°C) can be deducted from the

following relation:

TJ = 75 + 1---0-.-2-.-0---–0---3-V--8--T-4---J-

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 2.9V. About

300mV 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.
