1.3. Description:
【1】 DC-IN: DC power jack. It is designed to provide convenience for demo. Simply one adapter is needed for supplying the EVM board to light up the Power LEDs. 【2】 D1: Reverse protection diode. It is located between input port of the EVM, VIN, and Vcc pin of the IC. The function is to provide protection when input source is reverse connected. 【3】 J1: Lighting mode selection connector. Four lighting modes of the 2 LEDs can be accomplished through jumper. The 2 LEDs can be connected in series or parallel, or either of the 2 LEDs can be selected. The method of selecting one of these modes is shown in the following table.
