This document introduces the features of the power module based on STEVAL-ISA099V1 demonstration board, which adopts L7986 chip, supports 3A output current, input voltage range from 4.5V to 38V, and output voltage can be adjusted from 0.6V to VIN.
The document details the STEVAL-ISA099V1 demonstration board, which is designed as a step-down switching power supply. It utilizes the L7986 integrated circuit in a DFN10 package to deliver up to 3 A of current to the load.
Key features include an input voltage range from 4.5 V to 38 V and an adjustable output voltage starting from 0.6 V. The board supports programmable switching frequencies between 250 kHz and 1 MHz, along with internal soft-start, enable functionality, and protection against overcurrent and thermal issues.
