Quik-Start User's Guide Summary

General Description.
The SMB120EVAL kit is a fully functional printed circuit board designed to demonstrate all the features of the SMB120 Nonvolatile, 9-Ch Programmable DC/DC converter with integrated power management. The SMB120EVAL operates from a +4.2V supply (2.7V to 5.5V range) and includes eight switch-mode DC-DC converters and a 3.3V LDO. A precision internal voltage reference permits the DC-DC converters to be trimmed to within a 0.5% tolerance. All output voltage levels are user programmable through the I2C serial bus. The SMB120EVAL manages the power-on/off sequencing of the DC-DC converters in addition to output and battery monitoring, and margining. Power on/off of the converters along with many other programmable features is permitted through the I2C 2-wire bus interface.
[continued in the PDF]

Several key, user-configurable functions are:

1.
User-Programmable Output Voltage for 8 DC-DC converters.

2.
Power on/off sequence management.

3.
Battery Monitoring

4.
UV/OV detection on outputs

5.
Programmable nominal, high and low trim/margin voltages.

6.
Individual enable control over all 8 channels.

7.
Programmable sequence time slots for 8 supplies.

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.

8 Programmable DC-DC converters with Margining.

User-Selectable Supply Voltage source.

Status Indicators (LED) included for power, fault, etc.

Large PCB ground plane minimizes voltage errors

Intermediate bus to power all channels
