The SMM151-3EVAL kit is a fully functional printed circuit board designed to demonstrate all the features of the SMM151/2/3 Non-volatile, Single Supply Voltage Marginer and Current/Voltage Monitoring Family. The SMM151-3EV operates from +2.7V to +5.5V supply and includes a non-isolated DC-DC converter. An internal precision voltage reference permits the DC-DC converter to be trimmed to within a 1% tolerance. The SMM151-3EVAL manages the voltage monitoring, margining and trimming of the DC-DC converter output and the converter input current. Converter voltage margining, real-time output voltage and input current readings, along with many other programmable features, are permitted through the I2C 2-wire bus interface.

Several key, user-configurable functions are:
1.	Programmable nominal, high and low trim/margin voltages.
2.	Output voltage/input current and under-voltage monitoring.
3.	Over-Voltage (UV/OV) fault monitoring.
4.	User-programmable glitch filter duration.
5.	Wide supply voltage range (2.7V to 5.5V for margining/voltage sense, 4.0V to 15V for current sense).
6.	User-programmable 256-byte EEPROM.
Additional features included on the EVAL board:
	EZ connect Power and Signal pins.
	User-Programmable Interface connector to digitally control DC-DC converter Trim/Margin voltages, etc.
	1 Low-Profile, Non-Isolated DC-DC converter with Trim/Enable/Sense functions.
	28-pin QFN Spring-Loaded Socket for SMM151/2/3.
	Status Indicators (LED) for READY, FAULT#.
	Large PCB ground plane minimizes voltage errors.
