STEVAL-ISA094V1, Demonstration Board using L7981, 3 A step-down switching power supply in an HSOP8 package. The L7981 features an embedded power MOSFET and is capable of delivering up to 3 A of current to the load, depending on the application conditions. The input voltage can range from 4.5 V to 28 V, while the output voltage can be set from 0.6 V to VIN. Requiring a minimum number of external components, the device includes an internal 250 kHz switching frequency oscillator that can be externally adjusted up to 1 MHz
