• Dev Kit Description

  The STEVAL-ISA077V2 demonstration board is based on the L6920D high efficiency step-up converter as well as the external components required for a typical application.
  Startup is guaranteed at 1 V and the device operates down to 0.6 V. The output voltage can be adjusted from 2 V to 5.2 V and two fixed output voltages (3.3 V and 5 V) are also available.
