PINOUTS:-

  • +Vin 16        +Vin
  • EN 15        0V
  • 0V 14        0V
  • 0V 13        0V
  • 0V 12        0V
  • 0V 11        0V
  • No connect 10        FB
  • +Vout 9          +Vout

(the FB pin can be used to connect an external voltage feedback circuit)

TO CALCULATE R2 VALUES FOR OTHER DESIRED VOUT

VOLTAGES….

R2 (K) =((Vout/0.8) -1) x 10    E.G for….

15V       R2=178K

12V       R2=140K

9V        R2=102K5

5V        R2=52K5

3V3       R2=31K3

( use nearest preferred value 0.1% resistor or compromise on accuracy)

INPUT VOLTAGE RANGE=3.6  to 18VDC

OUTPUT VOLTAGE RANGE=0.8  to 16VDC

N.B. UNIT IS NORMALLY SUPPLIED WITH VR1 FITTED (R2 NOT FITTED)

FOR FIXED VOLTAGE, REMOVE VR1 AND FIT R2 PER DATASHEET

OR REMOVE VR1 AND FIT EXTERNAL RESISTOR OR PRESET BETWEEN

PINS 9 AND 10
