产品概述

描述

The STEVAL-A6983NV1 is an easy to use synchronous monolithic step-down regulator capable of delivering up to 3 A DC to the load.

The wide input voltage range makes the device suitable for a broad range of applications.

The STEVAL-A6983NV1 is based on a peak current mode architecture and is packaged in a QFN16 (3 x 3 mm) with internal compensation thus minimizing design complexity and size.

The device is designed for applications active during car parking, so it maximizes the efficiency at the light-load with the controlled output voltage ripple.

The STEVAL-A6983NV1 allows the switching frequency to be selected in the 200 kHz - 2.3 MHz range with optional spread spectrum for improved EMC.

The EN pin provides enable/disable functionality. The typical shutdown current is 2 μA when disabled.

As soon as the EN pin is pulled-up the device is enabled and the internal 1.3 ms soft-start takes place.

The STEVAL-A6983NV1 features Power Good opencollector that monitors the FB voltage.

Pulse by pulse current sensing on both power elements implements an effective constant current protection and thermal shutdown prevents thermal run-away.
