While connecting it between Trim and Vo+ will increase the output voltage. The following equations determine the external resistance to obtain the trimmed output voltage. 510 − 10.2( KΩ) ∆ 5.1 × Vnom × (100 + ∆ ) 510 = − − 10.2( KΩ) 1.225 × ∆ ∆ Radj − down = Radj −up ∆= Vnom − Vdesired × 100 Vnom V norm : Nominal output voltage. For example, to get 3.63V output, the trimming resistor is Radj −up = 5.1 × 3.3 × (100 + 10) 510 − − 10.2( KΩ) ＝89.9KΩ 1.225 × 10 10 The output voltage can also be trimmed by potential applied at the Trim pin. VO = (Vtrim + 1.225) × 2.69 V V Where trim is the potential applied at the Trim pin, and o is the desired output voltage. When trimming up, the output current should be decreased accordingly so as not to exceed the maximum output power and the minimum input voltage should be increased as shown in the following figures.

When wave soldering is used, the temperature on pins is specified to maximum 260°C for maximum 7s. When soldering by hand, the iron temperature should be maintained at 300°C ~ 380°C and applied to the converter pins for less than 10s. Longer exposure can cause internal damage to the converter. Cleaning of solder joint can be performed with cleaning solvent IPA or similative.
