Resistors connected between TRIM‐pin(6pin) to SENSE(+)‐pin (7pin) will increase the output voltage (Vo,adj) between 100% ~ 110% of the nominal output voltage(Vo,nom). (Vout‐Up control) Resistors connected between TRIM‐pin(6pin) to SENSE(‐)‐pin (5pin) will decrease the output voltage(Vo,adj) between 80% ~ 100% of the nominal output voltage(Vo,nom). (Vout‐Down control) The following equations give the required external‐resistor value to adjust the output voltage to Vo,adj. After calculating external resistance, it is necessary to check the output voltage and to adjust of the resistance value at your board conditions. 1) When you increase the output voltage, 5.1 Vo 100(%) Δ(%) 5.1 100(%) kΩ - 10.22 Radj - up ＝ Δ Δ (%) 1.225 (%) where, Vo, adj - Vo, nom Δ 100 (%) Vo, nom when you decrease the output voltage, 5.1 100(%) k Ω Radj - down ＝ - 10.22 Δ (%) where, Vo, nom - Vo, adj Δ 100 (%) Vo, nom If you change output voltage, it is necessary to evaluate the characteristics of DC‐DC converter at your board conditions.

MYBEA01210CZT□ 3 2 example Vin(-) ON/OFF or The voltage of maximum 5V appears in the ON/OFF pin at the time of pin opening. 6.8 External input capacitor When a inductance or a switch devise is connected to Input line, or when the transient response of input power supply is bad, input voltage is greatly changed at the time of load sudden change of DC‐DC converter. Since the load response of DC‐DC converter may not be normally demonstrated by this influence, and DC‐DC converter may cause unusual oscillation､in such a case, please connect an external input capacitor. 6.9 Output voltage remote sense It has the remote sense function which corrects a voltage drop by the line drop from the power supply output terminal to the load terminal . A voltage drop by the line drop can be corrected by connecting No.5 pin and No.7 pin to the load terminal part. At the time of a remote sense, a remote sense line is to use a shielding wire, a twist line, a side by side pattern, and so on , and reduce the influence of the noise. A Output Voltage Remote Sense Range is Vout (nom) within +5%. And, use an output voltage within the output adjustment range. Short‐circuit No.4 ‐No.5 terminal and No.7‐ No.8 terminal respectively when a remote sense shouldn't be necessary. If you use an output voltage remote sense, it is necessary to evaluate the characteristics of DC‐DC converter at your board conditions. Note: 1.
