PWM resolution defines how ... Fig. 4 is the block diagram for charging source detection. Two DACs are used to generate the 0.6V bias for the D+ and D- lines, and the voltage on the other ...

The circuit in Figure 1 shows a PWM (pulse-width-modulated) ramp generator that you can use in low-cost switch-mode dc/dc power supplies. Its supply voltage can range from 5 to 35V dc, and you can set ...
