NCP302155MNTWG Typical application Circuitry

NCP302155MNTWG

NCP302155MNTWG is a synchronous buck converter designed by ON Semiconductor, optimized for providing high efficiency and compact power management solutions in computing, telecommunications, and consumer electronics applications. Its integration of low RDS(on) MOSFETs, a compact package, and a wide input voltage range makes it particularly suitable for high-density power applications where space and efficiency are critical.

Application Scenario: Power Supply for Networking Equipment

A typical application for the NCP302155MNTWG is in the power supply circuits of networking equipment such as routers, switches, and modems, where it can efficiently convert a higher DC voltage to the lower voltages required by the device's digital circuits.

Parameter Features

-Integrated Low RDS(on) MOSFETs: Lower conduction losses increase efficiency.

- Broad Input Voltage Range: It can accept a range of input sources, which makes it adaptable to a variety of applications.

- Adjustable Output Voltage: Allows for flexible power supply designs tailored to specific circuit requirements.

- High Switching Frequency: This minimizes the total size of the power supply circuit by allowing the use of smaller external components.

Detailed Circuit Connection for Networking Equipment Power Supply

Input Voltage Connection

Connect the input voltage source, which could be derived from an AC-DC adapter or a main power bus, to the VIN pin (Pin 3) of the NCP302155MNTWG. This connection should be capable of providing the required input voltage range for the device.

Output Voltage Configuration

Connect feedback resistors from the VOUT pin (Pin 1) to the FB pin (Pin 2) to set the desired output voltage. The values of these resistors determine the output voltage based on the feedback mechanism detailed in the NCP302155MNTWG datasheet.

Grounding and Thermal Management

Ensure a solid connection of the PGND pins (Pins 8 and 9) and the AGND pin (Pin 4) to the system ground. Adequate thermal management should be provided, considering the thermal pad connected to the PGND pins to dissipate heat efficiently.

Bootstrap Capacitor for High-Side Drive

Attach a bootstrap capacitor between the BST pin (Pin 6) and the SW pin (Pin 7). This capacitor provides the necessary gate drive voltage for the high-side MOSFET, enabling efficient switching and minimizing dead-time losses.

Design Considerations

When designing a circuit with the NCP302155MNTWG for networking equipment power supplies, several important factors need to be considered:

- Input Voltage Stability: Ensure the input voltage is within the specified range of the NCP302155MNTWG and is stable under varying load conditions to maintain consistent output.

- Output Voltage Accuracy: Carefully select feedback resistor values to achieve the precise output voltage required by the networking equipment, accounting for tolerance and temperature variations.

- External Component Selection: Choose inductors and capacitors with appropriate ratings for current, voltage, and temperature to work efficiently with the high switching frequency and power levels of the NCP302155MNTWG.

- EMI and Layout Concerns: Minimize electromagnetic interference by optimizing the PCB layout, particularly around the high-switching paths, and by incorporating proper filtering and shielding techniques.

Incorporating the NCP302155MNTWG into the power supply design of networking equipment allows for the development of efficient, compact, and reliable power solutions, crucial for supporting the high-performance and continuous operation requirements of modern telecommunications infrastructure.
