L7987TR Buck Switching Regulator IC Positive Adjustable 0.8V 1 Output 3A 16-TSSOP (0.173", 4.40mm Width) Exposed Pad
Description:L7987TR
The L7987 device is a step-down monolithic switching regulator able to deliver up to 3 A DC. The output voltage
adjustability ranges from 0.8 V to VIN. The wide input voltage range and the 100% duty cycle capability meet the
fail safe specifications for industrial systems. The embedded switchover feature on the VBIAS pin maximizes the
efficiency at light load. The adjustable current limitation, designed to select the inductor RMS current accordingly
with the nominal output current, and the high switching frequency capability make the size of the application compact.
Pulse-by-pulse current sensing with digital frequency foldback implements an effective constant current protection over
the different application conditions. The peak current foldback decreases the stress of the power components in heavy
short-circuit condition. The PGOOD open collector output can also implement output voltage sequencing during the
power-up phase. Multiple devices can be synchronized sharing the SYNCH pin to prevent beating noise in low noise
applications like sensors with A/D conversion.
