Pin # Name Description
1 ON / OFF Input pin : Active low (less than 0.8V) to disable the device
2, 3, 4 Vin Power input
5, 6, 7, 8 GND Input and output ground (common)
9 , 10 Vout Power output
11 Vout (Auto Sense) If unused this pin must be connected to Pin 9 and 10
12 Vout-Adj With external resistors R1,R2 to selected output voltage
Tolerance:
± 0.25 mm
Package Style and Pinning (mm)
SIP12 PIN Package
Add a blocking diode to Vout if
current can flow backwards into
the output, as this can damage
the converter when it is powered
down. Protection diodes are re-
quired for high capacitive loads.
The diode can either be fitted
across the device if the source is
low impedance or fitted in series
with the output (recommended).
