Protection
If output is shorted , or output voltage is over the value specified in OVP ,
or DC-DC converter is heated abnormally, DC-DC converter will enter a hiccup
mode where it repeatedly turn on and off. After rejected the abnormal mode,
DC-DC converter will automatically restart. However output short, output over
voltage, and abnormal heating affect long-term reliability.

6.6 To Adjust Output Voltage
When TRIM-pin (6pin) is left open, DC-DC converter applies nominal output voltage.
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.

ON/OFF control
1) On control
ON/OFF Pin (2Pin) should be connected to Vin(-) Pin (3Pin), or keeps less than 0.7V.
2) Off control
ON/OFF Pin (2Pin) should be opened, or the current from ON/OFF Pin (2Pin) to Vin(-) Pin (3Pin) is controlled less than
30uA.

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.

13.2 Cleaning
13.2.1 When cleaning the products, please wash the products in isopropyl alcohol for up to 5 minutes using the dipping, boiling,
and vapor methods.
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.

13.4.3 Note prior to use
If you apply high static electricity, over rated voltage or reverse voltage to the products,
it macause defects in the products or degrade the reliability.
Please avoid the following items:
(1) over rating power supply, reverse power supply or not-enough connection of 0 V(DC)line
(2) electrostatic discharge by production line and/or operator
(3) electrified product by electrostatic induction
Do not give an excessive mechanical shock.
If you drop the products on the floor, etc., it may occur a crack to the core of inductors and monolithic ceramic
capacitors.
Do not give a strong shock such as a drop in handling.
Do not bend this product much more than 0.1mm.
13.5 Transportation
If you transport the products, please pack them so that the package will not be damaged by mechanical vibration or
mechanical shock,
and please educate and guide a carrier to prevent rough handling.
If you transport the products to overseas (in particular, by sea), it is expected that the transportation environment will be
the worst, so
please pack the products, in the package designed on the consideration of mechanical strength, vibration-resistant and
humidity-resistant.
The package of the products, which Murata sells in Japan, may not resist over sea transport.
Please consult us if you are to use the Murata package of the products sold in Japan for transport to overseas.
