Product overview
Description
The STEVAL-L6982CDR evaluation board is based on the L6982CDR synchronous monolithic step-down regulator capable of delivering up to 2 A DC to the load.
Its wide input voltage range makes the device suitable for a broad range of applications.
The device implements peak current mode architecture in an SO 8L package with internal compensation to minimize design complexity and size.
The L6982 is available in low consumption mode version (LCM) as L6982CDR and low noise mode version (LNM) as L6982NDR.
LCM maximizes efficiency at light load with controlled output voltage ripple, making the device extremely suitable for battery-powered applications.
LNM makes the switching frequency constant and minimizes the output voltage ripple overload current range, meeting the specification for noise sensitive applications.
The EN pin manages the enable/disable function. The typical shutdown current is 2 μA when disabled. When the EN pin is pulled up, the device is enabled and the internal 1.3 ms soft-start takes place.
Pulse-by-pulse current sensing on both power elements implements effective constant current protection while thermal shutdown prevents thermal run-away.
