Part Overview

Description
The MAX1730 is a regulated step-down charge pump that generates up to 50mA at fixed output voltages of 1.8V or 1.9V from an input voltage in the 2.7V to 5.5V range. It employs fractional conversion techniques to provide efficiency exceeding that of a linear regulator. The MAX1730 operates at up to 2MHz, permitting the use of small 0.22uF flying capacitors while maintaining low 75μA quiescent supply current. Proprietary soft-start circuitry prevents excessive current from being drawn from the supply during startup, making the MAX1730 compatible with higher impedance sources such as alkaline and lithium-ion cells.

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.

    1.9V
  • 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.

  • Height

    Height, in the context of electronic components, refers to the vertical dimension of the component. It is typically measured in millimeters (mm) or inches (in). Height is an important parameter to consider when designing and assembling electronic circuits, as it affects the overall size and form factor of the device. Components with a smaller height are often preferred for applications where space is limited, such as in portable devices or embedded systems.
