Surface Mount
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.

Surface Mount
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.

Number of Pins

Number of Pins: Indicates the number of electrical connections available on the component. These pins are used to connect the component to other components or circuits on a printed circuit board (PCB). The number of pins determines the functionality and connectivity options of the component. It is important to ensure that the component has the correct number of pins for the intended application.

Operating Temperature

Operating Temperature is the range of temperatures at which an electronic component can function properly. It is typically specified in degrees Celsius (°C) and indicates the minimum and maximum temperatures at which the component can operate without experiencing damage or degradation. Operating Temperature is an important parameter to consider when designing electronic circuits, as it ensures that the components will function reliably in the intended operating environment.

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.

Obsolete
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.

Function

Function refers to the primary purpose or role of an electronic component within a circuit. It describes the specific task or operation that the component is designed to perform. For example, a resistor's function is to limit current flow, a capacitor's function is to store electrical energy, and a transistor's function is to amplify or switch signals. Understanding the function of a component is crucial for selecting the appropriate component for a particular application and ensuring its proper operation within the circuit.

Step-Down
Number of Outputs

Number of Outputs refers to the number of independent output signals or channels that an electronic component can provide. It indicates the capability of the component to drive multiple external devices or circuits simultaneously. A higher number of outputs allows for greater flexibility and connectivity in electronic systems.

1
Output Voltage

Output Voltage is the voltage level produced by an electronic component when it is operating. It is typically measured in volts (V) and can be either positive or negative. The output voltage of a component is determined by its design and the input voltage applied to it. For example, a voltage regulator will produce a fixed output voltage regardless of the input voltage, while an amplifier will produce an output voltage that is proportional to the input voltage.

1.708V
Output Type

Output type refers to the type of signal or power that an electronic component can produce. It can be analog or digital, AC or DC, and can vary in voltage, current, or power levels. The output type is determined by the component's design and is crucial for matching it with other components in a circuit. Understanding the output type ensures proper signal processing, power delivery, and overall system functionality.

Output Configuration

Output Configuration refers to the arrangement of output terminals or pins on an electronic component. It specifies the number, type, and arrangement of these terminals, allowing for various connection options. This parameter is crucial for determining the component's compatibility with other devices and ensuring proper signal flow within a circuit.

Positive
Output Current

Output Current is the maximum amount of current that an electronic component can deliver to a load without exceeding its specified operating limits. It is typically measured in amperes (A) or milliamperes (mA). Output Current is a critical parameter for selecting electronic components, as it determines the amount of power that the component can provide to a load.

Quiescent Current

Quiescent current is the amount of current drawn by an electronic component when it is not actively performing its intended function. It is typically measured in milliamps (mA) or microamps (µA). Quiescent current is important because it can affect the overall power consumption of a circuit, especially in battery-powered devices. Components with high quiescent current can drain batteries more quickly than those with low quiescent current.

Length

Length, in the context of electronic components, refers to the physical dimension of a component along its longest axis. It is typically measured in millimeters (mm) or inches (in). Length is a crucial parameter for determining the physical size and space requirements of a component on a printed circuit board (PCB) or other assembly. It also affects the component's electrical characteristics, such as inductance and capacitance, which can be influenced by the length of conductors or traces within the component.

Description
The LM27213 is a single-phase synchronous buck regulator controller designed for portable microprocessors. It features on-chip gate drive for a compact solution and supports output currents exceeding 25 Amps. The IC employs a current mode hysteretic control mechanism with inductor current sensing through a low-value sense resistor. It operates over an input voltage range of 5V to 30V and offers a programmable output voltage ranging from 0.700V to 1.708V in 64 steps. The error in the output voltage directly sets the inductor current, resulting in optimal dynamic response to load transients. The hysteretic control provides excellent line transient response due to its intrinsic input voltage feedforward characteristic.
