STEVAL-ISA079V2:High-efficiency monolithic synchronous step-down regulator based on the L6928

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.

Key Features

  • 2.0 V to 5.5 V battery input range
  • High efficiency: up to 95%
  • Extremely low quiescent current
  • 1 μA max shutdown supply current
  • 800 mA max output current
  • Adjustable output voltage from 0.6 V
  • Low dropout operation: up to 100% duty cycle
  • ± 1% output voltage accuracy
  • 1.4 MHz switching frequency
  • Externally synchronizable from 1 MHz to 2 MHz
  • Short-circuit protection
  • RoHS compliant
