STEVAL-ISA094V1：3 A step-down switching power supply demonstration board based on the L7981 (HSOP8)
The STEVAL-ISA094V1 is a step-down switching power supply based on STMicroelectronics’ L7981 switching regulator 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.
