The STEVAL-ISA091V1 is step-down switching power supply based on STMicroelectronics’ L7980 switching regulator in a QFN package.


The L7980 features an embedded power MOSFET and is capable of delivering up to 2 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.

Key features
  • 2 A DC output current
  • 4.5 V to 28 V input voltage
  • Output voltage: 3.3 V (adjustable from 0.6 V)
  • 250 kHz switching frequency, programmable up to 1 MHz
  • Internal soft-start and enable
  • Low dropout operation: 100% duty cycle
  • Voltage feed-forward
  • Zero load current operation
  • Overcurrent and thermal protection
  • RoHS compliant
