General Description The SMM665EVAL kit is a fully functional printed circuit board designed to demonstrate all the features of the SMM665 Nonvolatile, Programmable six-Channel Power Supply Active DC Output Controller (ADOCTM), Monitor and Sequencer. The SMM665EV operates from either a +5V or a +12V supply and includes six non-isolated DCDC converters. A precision voltage reference permits the DC-DC converters to be trimmed to within a 0.2% tolerance.
The SMM665EVAL manages the power-on/off sequencing of the DC-DC converters in addition to voltage monitoring, margining and trimming of the onboard converters. Power on/off of the converters along with many other programmable features is permitted through the I2C 2-wire bus interface.

 

Several key, user-configurable functions are:

1. Power on/off sequence management 2. User-Programmable Voltage Sensor with Under-Voltage or Over-Voltage (UV/OV) fault monitoring (5mV increments) 3. Programmable assertion levels of management input/output pins 4. Programmable nominal, high and low trim/margin voltages 5. Programmable power-on/off intervals 6. Programmable sequence time slots for all 6-channels Additional features included on the EVAL board: EZ connect Power and Signal pins User-Programmable Interface connector to digitally control power supply voltages, sequencing, etc. 6 Low-Profile, Non-Isolated DC-DC converters with Trim/Enable/Sense Functions 48-pin TQFP Spring-Loaded Socket for SMM665 Status Indicators (LED) included for power, fault, etc. Large PCB ground plane minimizes voltage errors
