LTC1629/LTC1629-PG
RUN/SS (Pin 1):
Combination of Soft-Start, Run Control
Input and Short-Circuit Detection Timer. A capacitor to
ground at this pin sets the ramp time to full current output.
Forcing this pin below 0.8V causes the IC to shut down all
internal circuitry. All functions are disabled in shutdown.
SENSE1
+
, SENSE2
+
(Pins 2,14):
The (+) Input to the
Differential Current Comparators. The I
TH
pin voltage and
built-in offsets between SENSE
and SENSE
+
pins in
conjunction with R
SENSE
set the current trip threshold.
SENSE1
, SENSE2
(Pins 3, 13):
The (–) Input to the
Differential Current Comparators.
EAIN (Pin 4):
Input to the Error Amplifier that compares
the feedback voltage to the internal 0.8V reference voltage.
This pin is normally connected to a resistive divider from
the output of the differential amplifier (DIFFOUT).
PLLFLTR (Pin 5):
The Phase-Locked Loop’s Low Pass
Filter is tied to this pin. Alternatively, this pin can be driven
with an AC or DC voltage source to vary the frequency of
the internal oscillator.
