Description
General part information
STEVAL-1PS03A Series
The STEVAL-1PS03A is an evaluation board for a smart converter design able to deliver up to 400 mA output current from a 1.8 V to 5.5 V input, with a dynamically adjustable 1.6 V to 3.3 V output voltage.
The board features the ST1PS03AQTR nano-quiescent miniaturized synchronous step-down converter which implements enhanced peak current control (PCC) and advanced design circuitry to minimize quiescent current.
The device embeds a controlled load switch to supply a subsystem with VIN_AUX voltage rail. The board demonstrates how highly efficient conversion can be achieved with just the ST1PS03AQTR, a 2.2 μH inductor and two small capacitors.
