STEVAL-ISA079V1

High efficiency monolithic synchronous step-down regulator based

on the L6928D

Data brief

Features

synchronizable from 1 MHz to 2 MHz

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.
