How Auto-Track Works
Auto-Track works by forcing the module output voltage to follow a voltage presented at the
Track
control pin
(1)
.
This control range is limited to between 0 V and the module set-point voltage. Once the track-pin voltage is
raised above the set-point voltage, the module output remains at its set-point
(2)
. As an example, if the
Track
pin
of a 2.5-V regulator is at 1 V, the regulated output is 1 V. If the voltage at the
Track
pin rises to 3 V, the regulated
output does not go higher than 2.5 V.

Under Auto-Track control, the regulated output from the module follows the voltage at its
Track
pin on a
volt-for-volt basis. By connecting the
Track
pin of a number of these modules together, the output voltages follow
a common signal during power up and power down. The control signal can be an externally generated master
ramp waveform, or the output voltage from another power supply circuit
(3)
. For convenience, the
Track
input
incorporates an internal RC-charge circuit. This operates off the module input voltage to produce a suitable rising
waveform at power up.
