Description

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.
