L6928D Monolithic Synchronous Step-Down Regulator Demonstration Board

The STM-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. 2 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
