Isolated DC-DC converter for PoE PD

http://www.murata.com/products/power

Detection and Hardware Classification

DC-DC converter implements IEEE 802.3af compliant detection and

hardware classification.

When DC-DC converter(PD) is connected to PSE, the PSE applies

two voltages in the range of 2.8 V to 10 V and measures the

corresponding current. Connection to PD is detected by measured

current.(Detection)

After Detection, the PSE applies voltage in the range of 15.5 V to

20.5 V and measures the corresponding current. PD is classified by

measured current.(Hardware Classification)

Please check with your application.

SMT Reflow Soldering Guidelines

The surface-mount reflow solder profile is shown below.

This graph should be used only as a guideline.

Reflow Soldering Profiles : JEDEC IPC/JEDE J-STD-020D

Do not vibrate for the products on reflow. Please need to take care

temperature control because mounted parts may come off if the

product is left under the high temperature. Do not mount on

backside of the board.

Many other factors influence the success of SMT reflow soldering.

Since your production environment may differ, please thoroughly

review these guidelines with your process engineers.

Storage

Please store this product in an environment where the

temperature/humidity is stable in the range 0 to 40°C/10 to

75%RH and no direct sunlight. Use the product within 6 months

after delivery.

Please avoid storage conditions where humidity and temperature

change rapidly, as that may cause condensation on the product,

which might degrade the quality of the product.

Please do not store the product environments that are dusty, in

direct exposure to sea breeze, or in an atmosphere containing

corrosive gas (Cl2, NH3, SO2, NOX and so on).

Operational environment and operational conditions

This product is not chemical-proof or rust-proof.

In order to prevent this product from leakage of electricity and/or

abnormal temperature increase, do not use the product 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).

Operational Conditions

Please use the product within specified values (power supply,

temperature, input, output and load condition etc.). Input voltage

drops for line impedance, so please make sure that input voltage is

within in specified values.

If the product is used over the specified values, it may damage the

product, reduce the quality, and even if the products can endure the

condition for short time, it may cause degradation of the reliability.
