  • The A6986 device is a step-down monolithic switching regulator able to deliver up to 2 A DC. The output voltage adjustability ranges from 0.85 V to VIN. The 100% duty cycle capability to withstand the cold crank event and the wide input voltage range make the A6986 device ideal for battery powered automotive systems. The “Low Consumption Mode” (LCM) is designed for applications active during car parking, so it maximizes the efficiency at the light-load with the controlled output voltage ripple. The “Low Noise Mode” (LNM) makes the switching frequency constant and minimizes the output voltage ripple overload current range, meeting the low noise application specification like car audio. The output voltage supervisor manages the reset phase for any digital load (μC, FPGA). The RST open collector output can also implement output voltage sequencing during the power-up phase. The synchronous rectification, designed for high efficiency at the medium - heavy load, and the high switching frequency capability makes the size of the application compact. Pulse-by-pulse current sensing on both power elements implements effective constant current protection.
