Description

The STEVAL-ISA079V2 demonstration board is

based on the L6928 DC-DC monolithic regulator,

specifically designed to provide extremely high

efficiency.

The L6928 supply voltage can be as low as 2.0 V,

allowing its use in single Li-Ion cell supplied

applications.

The output voltage can be selected by an external

divider down to 0.6 V. The duty cycle can saturate

to 100%, allowing low dropout operation.

Note:

Previous part number EVAL6928Q1
