Pin Functions
Vin (Pin 1 – 4, 25): Input Voltage, 3 – 13.2V.
Pgnd (Pin 6-14, 24):
Power Ground.
+VS (Pin 22): Positive Sense Lead. Connect to the
positive point close to the load.
-VS (Pin 21): Negative Voltage Sense lead. Connect
to the negative point close to the load.
Trim (Pin 20):
Output voltage trim.
With no
connection the output voltage is set to 1.3 V.
VREF (Pin 19): Internal reference voltage, 5V, output
can be used to generate outputs <1.3V.
Enable (Pin 15):
Enable input. Internally pulled to
Vin.
When left floating, the converter is enabled
(ON). With enable connected to the ground or pulled
low the converter is disabled (OFF).
OCPA and OCPB (Pins 16, 17):
Output Current
Limit Adjustment, using a resistor and a capacitor.
VOUT (Pin 18, 23): Output Voltage. Use pin 23 for
high current connection to the load, pin 18 for OCP
adjustment.
VLDO (Pin 5): Internal supply voltage. Connect to an
external voltage source >5.2V, if the input voltage is
below 5.2V.
