Product overview

Description

The STEVAL-ISA079V1 demonstration board is based on the DC-DC monolithic regulator L6928D, specifically designed to provide extremely high efficiency.

The L6928D supply voltage can be as low as 2 V, allowing it to be used in single Li-Ion cell supplied applications.

Output voltage can be selected by an external divider down to 0.6 V.

Duty cycle can saturate to 100%, allowing low dropout operation.

The previous part number for this demonstration board was EVAL6928D.
