Product overview
Description
This data brief provides an overview of the use of the STEVAL-LEOPOL1V1 evaluation board, created and optimized for a typical application of the LEOPOL1 device, a single phase, step-down monolithic switching regulator with high precision internal voltage reference and integrated power MOSFETs for synchronous conversion.
The regulator LEOPOL1 converts 3 V ~ 12 V input voltage to 0.8 V ~ (0.85 x VIN) output voltage. The controller is based on a peak current mode architecture, which ensures a fast load transient response and very stable switching frequency. An embedded integrator compensates the DC voltage error due to the output voltage ripple.
