SMB111 Evaluation Kit
Quik-Start User's Guide Summary

General Description.
The SMB111EVAL kit is a fully functional printed circuit board designed to demonstrate all the features of the SMB111 Nonvolatile, 4-Ch Programmable DC/DC converter with integrated power management. The SMB111EVAL operates from a +4.2V supply (2.7V to 5.5V range) and includes four switch-mode DC-DC converters. 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 SMB111EVAL 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.

Several key, user-configurable functions are:
1.	User-Programmable Output Voltage for 4 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 4 channels.
7.	Programmable sequence time slots for 4 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.
	4 Programmable DC-DC converters with Margining.
	User-Selectable Supply Voltage source.
	Status Indicator (LED) for Sequence Complete.
	Large PCB ground plane minimizes voltage errors
	Individual Jumper disable for all channels.
