STEVAL-ISA190V1

The STEVAL-ISA190V1 is a 38V, 1.5A synchronous step down switching regulator evaluation board based on A6986F. The device is capable of delivering up to 1.5A and its 100% duty cycle capability to withstand the cold crank event along with its wide input operating voltage range make A6986F ideal choice for battery powered automotive systems. Synchronous rectification improves efficiency at full load as well as application compactness while high frequency switching (programmable up to 2MHz) lowers power passive costs and size while remaining outside of the AM band. The default evaluation board settings are 6V output voltage configured in LCM, 500KHz switching frequency, high level ISKIP current and the switchover feature disabled. This configuration can easily be changed by the user to evaluate different application scenarios.
