: Do not use the converter over its rated output power; care must be taken
when output voltage is adjusted up as it could significantly affect output power.
Vout = 3.3 - 15.53 / (39.6 + Rb)
Rb = 15.53 / (3.3 - Vout) - 39.6
Vout = 5.01 - 52.55 / (31.8 + Rb)
Rb = 52.55 / (5.01 - Vout) - 31.8
Vout = 12.01 - 431.1 / (57 + Rb)
Rb = 431.1 / (12.01 - Vout) - 57
Vout = 12.02 - 968.5 / (103 + Rb)
Rb = 968.5 / (12.02 - Vout) - 103

＝Vout 3.3 + 9.59 / (32 + Ra)
Ra = 9.59 / (Vout - 3.3) - 32
Vout = 5.01 + 17.64 / (17.8 + Ra)
Ra = 17.64 / (Vout - 5.01) - 17.8
Vout = 12.01 + 50.53 / (16.9 + Ra)
Ra = 50.53 / (Vout - 12.01) - 16.9
Vout = 12.02 + 53.55 / (18 + Ra)
Ra = 53.55 / (Vout - 12.02) - 18

It is possible to adjust the output voltage by connecting a resistor
between the TRM terminal and either the -Vout terminal or the +Vout terminal as shown below.

(6) TRM
(5) -Vout
Ra
Increase output voltage Decrease output voltage
(6) TRM
Connect resistor(Rb) between TRM( 6)and +Vout(7) as below formula.
Connect resistor(Ra) between -Vout(5) and TRM(6) as below formula.
