High Efficiency Monolithic Synchronous Step-down Regulator Board based on the L6928D
Manufactured By:ST Microelectronics
Part Number:STEVAL-ISA079V1
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.
