产品概述

描述

The STEVAL-ISA188V1 is a product evaluation board based on the ST synchronous step-down switching regulator A6986F3V3, which can deliver up to 1.5 A and, with its 100% duty cycle ability to withstand cold crank events and wide input operating voltage range, represents the ideal choice for battery-powered automotive systems. Synchronous rectification helps achieve higher efficiency at full load as well as application compactness, while high-frequency switching (programmable up to 2 MHz) helps reduce the cost and size of power passive components while remaining outside the AM band. The device can operate in low consumption mode (LCM), with a quiescent current of 30 μA that ensures high efficiency under light load, which is a requirement in typical car body applications that are active when a car is parked. A low noise mode (LNM) can be selected to meet the requirements of infotainment applications with forced PWM mode under all load conditions. The default board configuration is LCM active, 500 kHz switching frequency, high ISKIP current and the switchover feature enabled, but all of these settings can be easily changed so the user can evaluate different application scenarios.
