    PCI-PWM02 Users Manual (Rev 1.4) 1. PCI-PWM02 Block Diagram In the case of PCI-PWM02, as shown in [Figure 1-1], four digital PWM (Pulse Width Modulation) control blocks are configured to interface with the outside. PWM is widely used to control the speed control of DC motor and adjust the light quantity of lighting products such as LED by controlling the average voltage by changing the duty ratio within a certain period.
