Description

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 V

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.
