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 Radj - up＝ - 10.22 1.225Δ(%) Δ(%) where, Δ Vo, adj - Vo, nom 100(%) Vo, nom when you decrease the output voltage, 5.1 100(%) kΩ Radj - down＝ - 10.22 Δ (%) where, Δ Vo, nom - Vo, adj 100(%) Vo, nom If you change output voltage, it is necessary to evaluate the characteristics of DC-DC converter at your board conditions.

MYBEA01212AZT 2 example 3 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.

Please inform us if you are to use aqueous or semi-aqueous cleaning or another methods. Do not use ultrasonic cleaning because semiconductor device on the products, bonding wires may be broken by resonance. 13.2.2 After cleaning, please dry the products thoroughly. If you touch the products that have not been dried enough yet, you need to take care because the marking of the products may get thin or blurred. Do not measure electrical characteristics, until the products get dried enough. 13.2.3 If you use no-cleaning type flux and you don’t clean our products, please confirm the reliability of the products fully in advance. 13.3 Storage 13.3.1 Please store the products in room where the temperature/humidity is stable and direct sunlight cannot come in and use the products within 6 months after delivery. Avoid damp heated places or such places where there are large temperature changes, because water may condense on the products, the characteristics may be reduced in quality, and/or be degraded in the solderability. If you store the products for a long time (more than 1 year), use caution because the products may be degraded in the solderability and/or rusty. Please confirm solderability and characteristics for the products regularly. 13.3.2 Please do not store the products in the places such as: in a dusty place, in a place exposed directly to sea breeze, in an atmosphere containing corrosive gas (Cl2,NH3,SO2,NOX and so on). 13.4 Operational Environment and Operational Conditions 13.4.1 Operational Environment The products are not waterproof, chemical-proof or rustproof. In order to prevent leakage of electricity and abnormal temperature increase of the products, do not use the products under the following circumstances: (1) in an atmosphere containing corrosive gas (Cl2, NH3, SO2, NOX and so on) (2) in a dusty place (3) in a place exposed to direct sunlight (4) in such a place where water splashes or in such a humid place where water condenses (5) in a place exposed to sea breeze (6) in any other places similar to the above (1)through (5) 13.4.2 Operational Conditions Please use the products within specified values (power supply, temperature, input, output and load condition, and so on). Input voltage drop for line impedance, so please make sure that input voltage is included in specified values. If you use the products over the specified values, it may break the products, reduce the quality, and even if the products can endure the condition for short time, it may cause degradation of the reliability.
