STEVAL-ISA099V1 3 A step-down switching demonstration board based on the L7986 in DFN10 package
The STEVAL-ISA099V1 demonstration board is a step-down switching power supply based on the L7986 in DFN10 package.
The L7986 is a step-down regulator with a 3.7 A (minimum) current limited embedded power MOSFET, so it is able to deliver up to 3 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.
