The STEVAL-1PS01EJR evaluation board features the ST1PS01 nano-quiescent miniaturized synchronous step-down converter that is designed for applications where high efficiency, PCB size and thickness are key factors.


The converter can provide up to 400 mA output current with an input voltage ranging from 1.8 V to 5.5 V. The output voltage can be dynamically adjusted from 1.8 V to 3.3 V using two digital control inputs.


Thanks to the enhanced peak current control (PCC), the ST1PS01 can achieve very high conversion efficiency using only a 2.2 µH inductor and two small capacitors.


The advanced design circuitry minimizes quiescent current.
