Description
General part information
STEVAL-1PS02D Series
The STEVAL-1PS02D evaluation board allows evaluation of a smart converter able to deliver up to 400 mA output current from a 1.8 to 5.5 V input, with a dynamically adjustable 1.0 to 1.35 V output voltage.
The board embeds the ST1PS02DQTR nano-quiescent miniaturized synchronous step-down converter which implements enhanced peak current control (PCC) and advanced design circuitry to minimize quiescent current. It features a controlled load switch to supply a subsystem with the same voltage rail. The device is supplied in TQFN12 (2.0x1.7 mm) thin package, but other packages are also available.
The board demonstrates how highly efficient conversion can be achieved using just the ST1PS02DQTR, a 2.2 μH inductor and two small capacitors.
