Description

  • STEVAL-ISA207V1, Evaluation Board is a step-down switching power supply based on the A7987 regulator in an HTSSOP16 package. It is designed for automotive system battery-powered applications. The output voltage can be set starting from 0.8V. Almost low drop-out operation, due to the advanced integrated switch management, can be achieved. The A7987 is a 61V, 3A step-down asynchronous switching regulator with embedded high-side power MOSFET is capable of delivering up to 3A of current, depending on the application conditions. The embedded switchover feature on the VBIAS pin and the light load management (pulse skipping) are included to maximize power conversion efficiency across the entire load range, and the soft-start current limit threshold and switching frequency can be adjusted according to specific application requirements
