High-efficiency monolithic synchronous step-down regulator based on the L6928
  • active Active

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.
