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 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.
