Data Sheet Jul. 20, 2010 15W, Dual Output Input Source Impedance The power module should be connected to a low impedance input source. Highly inductive source impedance can affect the stability of the power module. The addition of an external C-L-C filter is recommended to minimize input reflected ripple current. The inductor is simulated source impedance of 12μH and capacitor is Nippon chemi-con KZE series 10μF/100V&10μF/100V.
Data Sheet Jul. 20, 2010 15W, Dual Output Short Circuit Protection Continuous, hiccup and auto-recovery mode. During a short circuit condition the converter will shut down. The average current during this condition will be very low and damage to this device should not occur. Thermal Consideration The power module operates in a variety of thermal environments. However, sufficient cooling should be provided to help ensure reliable operation of the unit.
Data Sheet Jul. 20, 2010 15W, Dual Output Remote ON/OFF Control The Remote ON/OFF Pin is used t o turn the DC/DC power module on and off. The user must connect a switch between the on/off pin and the Vi (-) pin. The switch can be an open collector transistor, FET, or Photo-Coupler. The switch must be capable of sinking up to 1 mA when using a low logic level voltage. When using a high logic level, the maximum signal voltage is 15V and the maximum allowable leakage current of the switch is 50 uA.
