Monolithic Power Systems (MPS) EVQ3367A Evaluation Board

Monolithic Power Systems (MPS) EVQ3367A Evaluation Board is designed to demonstrate the capabilities of the MPQ3367A. The MPQ3367A is a step-up converter with a six-channel current source designed to drive white LED array drivers as backlighting for small and medium-sized LCD panels. This device features 6 channels with a maximum of 150mA per channel, internal 100mΩ, 50V MOSFET, and up to 2.2MHz configurable f_SW. The EVQ3367A evaluation board is available in 63.5mm x 52.5mm (LXW) dimensions.
