STMicroelectronicsSTEVAL-ISA100V1Cartes et kits de développement de gestion de la puissance

The STEVAL-ISA100V1 demonstration board is a step-down switching power supply based on the L7986A in HSOP8 package. The L7986A is a step-down switching 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.
