The STEVAL-ISA185V1 is a product evaluation board based on the ST synchronous step-down switching regulator A6985F3V3, which can deliver up to 0.5 A and, with its 100% duty cycle ability to withstand cold crank events and wide input operating voltage range, renders the A6985F3V3 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 to 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, hence ensuring the high efficiency under light load condition required in typical car body applications that are active during car parking. 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, 2 MHz 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.
