Highly inductive source impedance can affect the stability of the power module.
Data Sheet Jul. 20, 2010 15W, Single Output Output Voltage Adjustment Output voltage set point adjustment allows the user to increase or decrease the output voltage set point of a module. This is accomplished by connecting an external resistor between the TRIM pin and either the Vo (+) or Vo (-) pins. With an external resistor between the TRIM and Vo (-) pin, the output voltage set point increases. With an external resistor between the TRIM and Vo (+) pin, the output voltage set point decreases.
Data Sheet Jul. 20, 2010 15W, Single 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, Single 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.
