10W, Dual Output Input Source Impedance The converter should be connected to a low impedance input source. Highly inductive source impedance can affect the stability of the converter. Input external L-C filter is recommended to minimize input reflected ripple current. The inductor has a source impedance of 12μH and capacitor is Nippon chemi-con KY series 100μF/100V. The capacitor must be located as close as possible to the input terminals of the converter for lowest impedance.
PAGE 21
10W, Dual Output Thermal Consideration The converter operates in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat is removed by conduction, convection, and radiation to the surrounding environment. Proper cooling can be verified by measuring the point as shown in the figure below. The temperature at this location should not exceed 100°C.

10W, Dual Output Remote ON/OFF Control (Option) Remote control is an optional feature. Positive logic: Turns the module On during logic High on the On/Off pin and turns Off during logic Low. Negative logic: Turns the module On during logic Low on the On/Off pin and turns Off during logic High. The On/Off pin is an open collector/drain logic input signal (Von/off) that referenced to -VIN.

10W, Dual Output Safety and Installation Instruction Fusing Consideration Caution: This converter is not internally fused. An input line fuse must always be used. This encapsulated converter can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a sophisticated power architecture. For maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse.
