データブリーフのダウンロード

The STEVAL-ISA097V1 demonstration board is a step-down switching power supply based on the L7985 in DFN10 package.

The L7985 is a step-down regulator with a 2.5 A (minimum) current limited embedded power MOSFET, so it is able to deliver up to 2 A current to the load depending on the application conditions.

The input voltage can range from 4.5 V to 38 V, while the output voltage can be set starting from 0.6 V to VIN.

Requiring a minimum set 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
  • From 4.5 V to 38 V range input voltage
  • Output voltage 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
