Description

The 1N5385B is 170V, 5W, Zener Diode.

The 1N5333B through 1N5388B JEDEC registered series of axial-leaded 5.0 watt Zeners provides a selection from 3.3 to 200 volts with different tolerances as identified by specific suffix letter on the part number.

These plastic encapsulated Zeners have a moisture classification of “Level 1” with no dry pack required. They may be operated at high maximum dc currents with adequate heat sinking due to their comparatively low thermal resistance design. Microsemi also offers numerous other Zener products to meet higher and lower power applications.

MP1482 PDF Datasheet – Step-Down Converter

Posted on by pinout

A synchronous rectified step-down converter, also known as a synchronous buck converter, is a type of DC-DC (Direct Current to Direct Current) converter commonly used in power electronics. It is designed to efficiently step down a higher voltage to a lower voltage while minimizing power losses.

The synchronous rectified step-down converter typically consists of a high-side MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor), a low-side MOSFET, an inductor, and a diode. The operation of the converter involves switching the MOSFETs to control the flow of current through the inductor, thus stepping down the voltage.

Part Number: MP1482

Function: 2A 18V Synchronous Rectified Step-Down Converter

Package: SOP 8 Pin Type

Manufacturer: Monolithic Power Systems ( https://www.monolithicpower.com/ )

Description

The MP1482 is a monolithic synchronous buck regulator. The device integrates two 130mΩ MOSFETs, and provides 2A of continuous load current over a wide input voltage of 4.75V to 18V. Current mode control provides fast transient response and cycle-by-cycle current limit. An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current drops to 1μA.
