® ISL6550A, ISL6550B, ISL6550C Data Sheet July 2003 FN9036.2 SAM (Supervisor And Monitor) The ISL6550 is a precision, flexible, VID-code-controlled reference and voltage monitor for high-end microprocessor and memory power supplies. It monitors various input signals, and supervises the system (typically a DC/DC converter) with its output signals. See the Block Diagram for reference. The ISL6550 includes a 5-bit DAC (Digital-to-Analog Converter), which is programmed by the five VID inputs. The voltage range of the BDAC (Buffered DAC output) is determined by the DACHI and DACLO voltage levels, which are externally adjustable through the R1, R2, R3 resistor divider network. VREF5 is a precision-trimmed 5V reference, and is used to set the voltage at the top of the resistor divider.
