Description
General part information
A6986 Series
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 and the wide input voltage range meet the cold crank and load dump specifications for automotive systems. The "Low Consumption Mode" (LCM) is designed for applications active during car parking, so it maximizes the efficiency at light load with 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 medium - heavy load, and the high switching frequency capability make the size of the application compact. Pulse by pulse current sensing on both power elements implements an effective constant current protection.AECQ100 qualification2 A DC output current4 V to 38 V operating input voltageLow consumption mode or low noise mode30 µA IQ at light load (LCM VOUT= 3.3 V)8 µA IQ-SHTDWNAdjustable fSW(250 kHz - 2 MHz)Output voltage adjustable from 0.85 V to VINEmbedded output voltage supervisorSynchronizationAdjustable soft-start timeInternal current limitingOvervoltage protectionOutput voltage sequencingPeak current mode architectureRDSON HS= 180 mO, RDSON LS= 150 mOThermal shutdown
