A6986H

A6986H Datasheet Automotive 38 V, 2 A synchronous step-down switching regulator with 30 μA quiescent current Product status link A6986H Features AEC-Q100 qualified 2 A DC output current 4 V to 38 V operating input voltage Low consumption mode or low noise mode 30 µA IQ at light-load (LCM VOUT = 3.3 V) 8 µA IQ-SHTDWN Adjustable fSW (250 kHz - 2 MHz) Fixed output voltage (3.3 V and 5 V) or adjustable from 0.85 V to VIN Embedded output voltage supervisor Synchronization Adjustable soft-start time Internal current limiting Overvoltage protection Output voltage sequencing Peak current mode architecture RDS(on) HS = 180 mΩ, RDS(on) LS = 150 mΩ Thermal shutdown Applications Designed for automotive systems Battery powered applications Car body applications (LCM) Car audio and low noise applications (LNM) Description The A6986H automotive grade 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 app...
