Application Notes
PTH03000 & PTH05000 Series
Power-Up Characteristics
When configured per their standard application, the
PTH03000 and PTH05000 series of power modules will
produce a regulated output voltage following the appli-
cation of a valid input source voltage. During power up,
internal soft-start circuitry slows the rate that the output
voltage rises, thereby limiting the amount of in-rush
current that can be drawn from the input source. The
soft-start circuitry introduces a short time delay (typi-
cally 10 ms) into the power-up characteristic. This is
from the point that a valid input source is recognized.
Figure 3-1 shows the power-up waveforms for a PTH05000W
(5-V input), with the output voltage set point adjusted for a
2-V output. The waveforms were measured with a 5-A
resistive load. The initial rise in input current when the
input voltage first starts to rise is the charge current drawn
by the input capacitors.

Output On/Off Inhibit
For applications requiring output voltage on/off control,
the PTH03000W & PTH05000W power modules in-
corporate an output on/off Inhibit control (pin 3). The
inhibit feature can be used wherever there is a require-
ment for the output voltage from the regulator to be
turned off.
The power module functions normally when the Inhibit
pin is left open-circuit, providing a regulated output
whenever a valid source voltage is connected to V in with
respect to GND .
Figure 3-2 shows the typical application of the inhibit
function. Note the discrete transistor (Q 1 ). The Inhibit
control has its own internal pull-up to V in potential. An
open-collector or open-drain device is recommended to
control this input.
Turning Q 1 on applies a low voltage to the Inhibit control
pin and disables the output of the module. If Q 1 is then
turned off, the module will execute a soft-start power-up
sequence. A regulated output voltage is produced within
20 msec. Figure 3-3 shows the typical rise in the out-
put voltage, following the turn-off of Q 1 . The turn off of
Q 1 corresponds to the fall in the waveform, Q 1 V gs . The
waveforms were measured with a 5-A resistive load.

Current Limit Protection
The PTHxx000W modules protect against load faults
with a continuous current limit characteristic. Under a
load fault condition the output current cannot exceed

the current limit value. Attempting to draw current that
exceeds the current limit value causes the output voltage
to be progressively reduced. Current is continuously
supplied to the fault until it is removed. Upon removal of
the fault, the output voltage will promptly recover.
Thermal Shutdown
Thermal shutdown protects the module’s internal circuitry
against excessively high temperatures. A rise in tempera-
ture may be the result of a drop in airflow, a high ambient
temperature, or a sustained current limit condition. If
the junction temperature of the internal components
exceed 150 °C, the module will shutdown. This reduces
the output voltage to zero. The module will start up
automatically, by initiating a soft-start power up when
the sensed temperature decreases 10 °C below the thermal
shutdown trip point.
