Description

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.
