Shown on this slide is a top level diagram of the ISL68200/01. At the heart of this family of controllers is Renesas' R4 analog modulator, offering good transient performance. Wrapped around this is a PMBus interface, with support for supply telemetry, including Vin, Vout, load current, and temperature; Vout on the fly setpoint adjustment; and fault reporting. In the lower left hand corner are the external configuration resistors. A simple resistor divider on each pin sets up all device parameters. These configuration resistors eliminate the need for non-volatile memory, removing the extra step of NVM configuration from the design flow.
