Monolithic Power Systems (MPS) MP4316A Synchronous Step-Down Converters

Monolithic Power Systems (MPS) MP4316A Synchronous Step-Down Converters are versatile and efficient step-down switching converters. The MP4316A offers a range of features suitable for various applications. Thanks to its current mode control, the device can provide up to 6A output current with a fast loop response. Integrated internal high-side and low-side power MOSFETs further simplify the design process, while the wide 3.3V to 45V input voltage range makes it ideal for use in automotive input environments.
