NOTE ON USE (Continued)

17. Please use within the power dissipation range below. Please also note that the power dissipation may changed by test

conditions, the power dissipation figure shown is PCB mounted.

Pd vs Operating Temperature

Pakage Body Temperature vs Operating Temperature

the power loss of micro DC/DC according to the following formula:

power loss = VOUT×IOUT×((100/EFFI) – 1) (W)

VOUT : Output Voltage (V)

IOUT : Output Current (A)

EFFI : Conversion Efficiency (%)
