The STEVAL-ISA205V1 product evaluation board is based on the synchronous step-down switching regulator A6986H that can deliver up to 2 A and withstand cold cranking across 100% duty cycle, which, along with its wide input operating voltage range, render the A6986H the ideal choice for battery powered automotive systems.

Synchronous rectification helps to achieve higher efficiency at full load as well as application compactness, while high-frequency switching (programmable up to 2 MHz) helps to cut power passive costs and size, while staying outside of the AM band.

The device can operate in a Low Consumption Mode (LCM) with a quiescent current down to 30 μA at VIN = 12 V and VOUT = 3.3 V, hence assuring high efficiency at light loads, as required in typical car body applications that are active during car parking.

A Low Noise Mode (LNM) is also available to meet the requirements of infotainment applications of forced PWM mode in all loading conditions.

The default configuration of the board is output voltage set to 3.3 V configured in LCM, 500 kHz switching frequency, ISKIP current set to high level and the switchover feature disabled. All of these settings can be easily changed by the user to evaluate different application scenarios.
