Mounting Type
Mounting Type refers to the method by which an electronic component is attached to a printed circuit board (PCB) or other surface. Common mounting types include:
* Through-hole: Component leads are inserted into holes in the PCB and soldered on the other side.
* Surface-mount: Component is placed on the surface of the PCB and soldered in place.
* Press-fit: Component is pressed into place on the PCB without soldering.
* Socket: Component is inserted into a socket on the PCB, allowing for easy replacement.
The mounting type is determined by factors such as the component's size, shape, and power requirements.

Package / Case
Package / Case refers to the physical housing or enclosure that encapsulates an electronic component. It provides protection, facilitates handling, and enables electrical connections. The package type determines the component's size, shape, pin configuration, and mounting options. Common package types include DIP (dual in-line package), SOIC (small outline integrated circuit), and BGA (ball grid array). The package also influences the component's thermal and electrical performance.

Series
Series, in the context of electronic components, refers to the arrangement of components in a circuit. When components are connected in series, they form a single path for current to flow through. The total resistance of a series circuit is the sum of the individual resistances of each component. Series connections are often used to control the flow of current in a circuit, as the total resistance can be adjusted by changing the number or type of components in the series.

Part Status
Part Status is an electronic component parameter that indicates the availability and production status of a component. It is typically used to inform customers about the availability of a component, whether it is in production, end-of-life, or obsolete. Part Status can also provide information about any restrictions or limitations on the component's use, such as whether it is only available for certain applications or if it has been discontinued.

Moisture Sensitivity Level (MSL)
Moisture Sensitivity Level (MSL) is a measure of the susceptibility of a surface mount electronic component to moisture-induced damage during soldering. It is classified into six levels, from 1 (least sensitive) to 6 (most sensitive). MSL is determined by the materials used in the component's construction, including the solderability of its terminals and the presence of moisture-absorbing materials. Components with higher MSL ratings require more stringent handling and storage conditions to prevent moisture absorption and subsequent damage during soldering.

Description
The LM22670 is a switching regulator that provides the necessary functions for implementing an efficient high-voltage step-down (buck) regulator with minimal external components. It incorporates a 42 V N-channel MOSFET switch capable of delivering up to 3 A of load current. The regulator features excellent line and load regulation, high efficiency (>90%), and voltage mode control for a wide ratio between input and output voltages. Internal loop compensation eliminates the need for external loop compensation components. Fixed 5 V output and adjustable output voltage options are available. The default switching frequency is 500 kHz, allowing for small external components and good transient response. The frequency can be adjusted from 200 kHz to 1 MHz with a single external resistor. The internal oscillator can be synchronized to a system clock or another regulator's oscillator. A precision enable input simplifies regulator control and system power sequencing. In shutdown mode, the regulator draws only 25 μA (typ). Built-in soft-start (500 μs, typ) eliminates the need for external components. The LM22670 also includes thermal shutdown and current limiting for protection against accidental overloads.
