9.2.2.4 Use With Analog Controllers

Figure 9-3 shows a synchronous buck converter application using an analog controller that provides level-shifted high-side control with the switch node as reference. The analog controller also generates the bootstrap voltage. In this use case, the level-shifted high-side control output, HO, from the controller may be directly connected to the input pin, LI, of the high-side LMG3100. The in-built level shifter and boot-strap circuits of the low-side LMG3100 are left unused.
