STEVAL-ISA198V1

STEVAL-ISA198V1 is a 2 A step down DC-DC switching regulator evaluation board based on the L7987L. The STEVAL-ISA198V1 product evaluation board is a step-down switching power supply based on the L7987L regulator in an HTSSOP16 package. The output voltage can be set starting from 0.8V. Low drop-out operation, due to the advanced integrated switch management, can be achieved. The L7987L is a 61V, 2A step-down asynchronous switching regulator with embedded power MOSFET capable of delivering up to 2 A of current, depending on the application conditions. The soft-start, current limit threshold and switching frequency are adjustable for application optimization.
