It is recommended to install C3 to improve performance. C1 & C2 are required and should be installed as close to the converter as possible Model Number Nominal Output (V) Vout Adjusted Up R2 (KΩ) Vout Adjusted Down R1 (KΩ) = (61 x Vout) -75.1 3.3 - Vout AMSRL-783.3-NZ 3.3 = 75.1 – (10 x Vout) Vout – 3.3 AMSRL-7805-NZ 5 = 90.72 – (10 x Vout) Vout – 5 = (61 x Vout) -90.72 5 - Vout AMSRL-7812-NZ 12 = 280.81 – (20 x Vout) Vout – 12 = (71 x Vout) -280.81 12 - Vout AMSRL-7815-NZ 15 = 269.37 – (15 x Vout) Vout – 15 = (66 x Vout) -269.37 15 - Vout If it is needed to adjust the output voltage higher or lower than the converter’s nominal value use the equations in the table above to calculate appropriate resistor values, insuring that the voltage is within the adjustment range for the converter used. If no voltage adjustment is needed connect a 470pF ceramic capacitor from pin 6 to ground. www.aimtec.com F 051e R8.E Tel: +1 514 620 2722 3 of 4 Toll free: + 1 888 9 AIMTEC (924 6832) North America only Series AMSRL-78-NZ Up to 7.5 Watt | DC-DC Switching Regulator Recommended Circuits Conducted and Radiated Emissions NOTE: 1.
