Description
The A7987 is a step-down monolithic switching regulator that can deliver up to 3 A
DC. The adjustable output voltage ranges from 0.8 V to VIN. The wide input voltage
range and the almost 100 duty cycle capability meet the fail-safe specifications for
automotive systems. The embedded switch-over feature on the VBIAS pin maximizes
efficiency at light load. The adjustable current limitation, designed to select the
inductor RMS current in accordance with the nominal output current, and the high
switching frequency capability make the size of the application compact. Pulse-bypulse
current sensing with digital frequency fold-back implements an effective
constant current protection over the different application conditions. The peak current
fold-back decreases the stress of the power components in heavy short-circuit
conditions. The PGOOD open collector output can also implement the output voltage
sequencing during the power-up phase. Multiple devices can be synchronized
sharing the SYNCH pin to prevent beating noise for low noise requirements such as
in infotainment applications.
