38 V, 1.5 A synchronous step-down switching regulator evaluation board based on the L6981NDR for industrial power systems
STMicroelectronics STEVAL-L6981NDR is based on the L6981NDR synchronous monolithic step-down regulator delivering up to 1.5 A DC.
Its wide input voltage range makes the solution suitable for a broad range of applications.
The device implements peak current mode architecture in a SO 8L package with internal compensation to minimize design complexity and size.
The L6981 is available in low consumption mode (LCM) and low noise mode (LNM) versions.
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.
