Basic Operation and Features
INPUT UNDER VOLTAGE LOCKOUT
To prevent any instability to the converter, which may affect the end system, the converter have been designed to turn-on once V
IN
is in the voltage range of 34-36 VDC. Likewise, it has also been programmed to turn-off when V
IN
drops down to 31-33.5 VDC.
OUTPUT VOLTAGE ADJUST/TRIM
The converter comes with a TRIM pin (PIN 6), which is used to adjust the output by as much as 90% to 110% of its set point. This
is achieved by connecting an external resistor as described below.
To
INCREASE
the output, external R
adj_up
resistor
should be connected between TRIM PIN (Pin6) and
+SENSE PIN (Pin 7). Please refer to Equation (1) for the
required external resistance and output adjust
relationship.
Equation (1a): 1.5V to 5V
Equation (1b): 1.2V
To
DECREASE
the output, external R
adj_down
resistor
should be connected between TRIM pin (Pin 6) and
-SENSE PIN (Pin 5). Please refer to Equation (2) for the
required external resistance and output adjust
relationship.
Equation (2):
Where:
% = percent change in output voltage
OUTPUT ENABLE
The converter comes with an Enable pin (PIN 2), which is primarily used to turn ON/OFF the converter. Both a Positive (no “N”
suffix required) and a Negative (suffix “N” required) Enable Logic options are being offered.
