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.

Active
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.

Frequency

Frequency, in the context of electronic components, refers to the rate at which an alternating current or voltage changes direction per second. It is measured in Hertz (Hz), which represents one cycle per second. Frequency is a crucial parameter for various electronic components, such as capacitors, inductors, and resonators. It determines the component's ability to store or release energy, filter signals, and resonate at specific frequencies. Understanding the frequency characteristics of electronic components is essential for designing and optimizing electronic circuits.

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 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.

Switching Frequency

Switching Frequency is the rate at which an electronic component, such as a transistor or MOSFET, switches between its on and off states. It is measured in Hertz (Hz) and represents the number of times per second that the component can change its state. A higher switching frequency allows for faster operation of electronic circuits and can improve efficiency. However, it can also increase power consumption and electromagnetic interference (EMI).

300kHz
Duty Cycle

Duty cycle is a parameter that describes the proportion of time that a signal is active in relation to its period. It is typically expressed as a percentage, with a duty cycle of 50% indicating that the signal is active for half of its period. Duty cycle is an important parameter in many electronic applications, such as power supplies, motor controllers, and audio amplifiers. By adjusting the duty cycle, it is possible to control the output power, speed, or volume of a device.

10 %
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.

The FAN5026 PWM controller provides high efficiency and regulation for two output voltages adjustable in the range from 0.9v to 5.5V that are required to power I/O, chip-sets, and memory banks in high-performance computers, set-top boxes, and VGA cards. Synchronous rectification contributes to high efficiency over a wide range of loads. Efficiency is even further enhanced by using MOSFET RDS(ON) as a current-sense component. Feedforward ramp modulation, average-current mode control scheme, and internal feedback compensation provide fast response to load transients. Out-of-phase operation with 180° phase shift reduces input current ripple. The controller can be transformed into a complete DDR memory power supply solution by activating a designated pin. In DDR Mode, one of the channels tracks the output voltage of another channel and provides output current sink and source capability — essential for proper powering of DDR chips. The buffered reference voltage required by this type of memory is also provided. The FAN5026 monitors these outputs and generates separate PGx (power good) signals when the soft-start is completed and the output is within 10% of its set point. Over-voltage protection prevents the output voltage from exceeding 120% of the set point. Normal operation is automatically restored when the over-voltage conditions cease. Under-voltage protection latches the chip off when either output drops below 75% of its set value after the soft-start sequence for this output is completed. An adjustable over-current function monitors the output current by sensing the voltage drop across the lower MOSFET. If precision current-sensing is required, an external current-sense resistor may be used.
