    PWM DC-DC converter ICs are an integral part of modern switch mode power supplies, power electronic circuits, and consumer electronic devices. There are a large number of electronic and power electronic circuits which require step-down or step-up DC-DC conversion. The higher switching frequencies of these converters ensure efficient power conversion and minimum conversion losses. These types of converter ICs are very commonly found in laptops, notebooks, televisions, monitors and other power distribution circuits.

    What is MP1496DJ?

    The MP1496DJ is a high frequency, synchronous, rectified, step-down, switch mode converter developed by MPS (Monolithic Power Solutions) Inc. This switch-mode step-down converter also features a built-in power MOSFET. This device operates on a wide range of input voltage and is capable of providing 2A of continuous output current with excellent line and load regulation. The device has multiple modes available. The synchronous mode operation ensures higher efficiency rates. Current mode operation provides loop stabilization and fast transient response. The device also includes standard protection features such as over-current protection, thermal protection, and soft start control. The IC requires minimum number of external components and comes in a compact 8-pin TSOT-23 package.
