The design procedure provided in this section is an example of electrical design. During the design process, be sure to comply with safety standards established by official bodies and with your company rules. * Repeat the operations check if a component constant changes after design has been completed. 3.2.1 MOSFET (Q1) The MOSFET receives the voltages shown in Figure 5. The maximum applied voltage nearly equals the maximum input voltage. In actual use, voltage spikes may occur—for instance, due to parasitic inductance of the wiring pattern. Check with the actual apparatus and select a component with sufficient withstand voltage. For a lighting apparatus that consumes a large amount of power, MOSFETs with low on-resistance offer advantages. When power consumption is small, MOSFETs with small capacitance, such as Ciss and Coss, help achieve highly efficient and advantageous dimming characteristics. IC power consumption is the product of the input voltage and current consumption. Current consumption is the sum of the logic current and the gate drive current. Select MOSFETs that have the lowest possible gate capacitance. (See Table 1 Recommended MOSFETs.) CAT.No.1A0202-2E |
