A versatile high-frequency switching regulator with an integrated high-side
high-voltage power MOSFET, the Monolithic Power Systems MP4559 step-down
converter is now available from Mouser stock. The device targets
applications such as high-voltage power conversion, automotive systems,
industrial, distributed and battery-power systems.
The MP4559 delivers 1.5A output with current mode control for fast loop
response and easy compensation. Input range is a wide 3.8V to 55V in order
to accommodate many step-down applications such as an automotive input
environment. 12µA quiescent current in shutdown mode makes the MP4559
suitable for battery powered applications. Higher power conversion
efficiency is achieved over a wide load range by scaling down the switching
frequency under light load conditions.
