Monolithic Power Systems (MPS) EVQ7200-L-00A Evaluation Board

Monolithic Power Systems (MPS) EVQ7200-L-00A Evaluation Board is designed for MPQ7200-AEC1, a high-frequency constant-current LED driver with power MOSFETs. This evaluation board offers a compact solution to achieve continuous output current, with line regulation and load over a wide input supply range. The MPQ7200-AEC1 switching frequency reduces ripple current and electromagnetic interference (EMI) in the buck mode. This MPQ7200-AEC1 is AEC-Q100 grade 1 qualified and is available in a QFN-19 (3mmx4mm) wettable flank package. The EVQ7200-L-00A evaluation board is a tested buck mode LED driver and is fully assembled. This evaluation board features Over-Current Protection (OCP) with latch off, fault indication for LED short, LED open, Output Over-Voltage (OOV), and thermal shutdown. The EVQ7200-L-00A evaluation board operates at a 3A output current and 6V to 42V input voltage range. This evaluation board is used in automotive LED lighting.
