STMICROELECTRONICS STEVAL-A6983CV1 Evaluation Board, A6983CQTR, Synchronous Step Down Regulator, Power Management

STEVAL-A6983CV1 is an evaluation board based on DC-DC converter buck regulator A6983CQTR. This is an easy to use synchronous monolithic step-down regulator capable of delivering up to 3A DC to the load. The wide input voltage range makes the device suitable for a broad range of applications. The STEVAL-A6983CV1 is based on a peak current mode architecture and is packaged in a QFN16 (3 x 3mm) 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-A6983CV1 allows the switching frequency to be selected in the 200KHz - 2.3MHz range with optional spread spectrum for improved EMC. The EN pin provides enable/disable functionality. The typical shutdown current is 2?A when disabled. The STEVAL-A6983CV1 features Power Good open collector that monitors the FB voltage.
