Product overview
Description
The STEVAL-LEOPOL1V1 is created and optimized for a typical application of the LEOPOL1.
The LEOPOL1 is a single phase, step-down monolithic switching regulator with high precision internal voltage reference and integrated power MOSFETs for synchronous conversion.
The LEOPOL1 regulator converts 3 ~ 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.
The STEVAL-LEOPOL1V1 is optimized to meet the radiation hardness required for low Earth orbit space.
It can operate in a wide operating temperature condition from -40 to 125°C
