how do i get 22 vdc out of this device. i followed the wiring per data sheet. i only get the source voltage on the output.

15v input 92 ohm pin 7 to 4 i'm getting 15 volts out.

In order to set the output voltage to 22V, the minimum input voltage must be Vin=(Vout+4).For 22Vout, minimum vin is 26V and maximum vin=36V.

Note 2 in the PTN78060H data sheet, For output voltages of 19 V and higher, the minimum input voltage is (VO + 4) V. See the Application Information for further guidance.

Maximum ouptu current at 22V is 2Amps

I THOUGHT THAT THIS DEVICE WILL STEP UP THE VOLTAGE. FROM 15 TO 22? NO.

The PTN78060W is a buck step down regulator.

The PTN78060A is a buck boost , + Vin to (-) vout maximum ouput voltage is (-15V).

Note 2 PTN78060A specification

(2) The maximum input voltage is limited and defined to be (32 - |VO|).

so. is the ptn78060a what i want to use to rise the power supply voltage from 12vdc to 24ish vdc. ?? i like the power supply that i'm using, but it's 13 vdc. the amp requires 24 vdc. ..

PTN78060A absolute maximum (-) output voltage is limited to (-15V). With (- 15V) Vout, input voltage range is minimum +9V to maximum +17V.
