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.

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.

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.

Output Power
Output Power is a measure of the electrical power delivered by an electronic component to a load. It is typically expressed in watts (W) or milliwatts (mW). The output power of a component is determined by its design and the voltage and current applied to it.
Output power is an important parameter for many electronic components, such as amplifiers, power supplies, and transmitters. It is used to determine the component's efficiency and to ensure that it can provide enough power to drive the load.

Fault Protection
Fault Protection is an electronic component parameter that indicates the component's ability to withstand and protect against electrical faults or abnormal conditions. It specifies the maximum fault current or voltage that the component can safely handle without sustaining damage or compromising its functionality. This parameter is crucial for ensuring the reliability and safety of electronic systems by preventing catastrophic failures and protecting sensitive components from damage.

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 MP157 is a primary side regulator that provides accurate constant voltage (CV) regulation without an opto-coupler. It supports Buck, Buck-Boost, Boost, and Flyback topologies. The integrated 500V MOSFET enables a simple structure and low cost. These features make the MP157 ideal for off-line low power applications, such as home appliances, standby power, and industrial control.
The MP157 operates in green mode, reducing peak current and switching frequency with decreasing load. This maintains excellent efficiency at light load, resulting in better average efficiency.
