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_IN.
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.
