The NCV7520FPR2G part is a current-mode PWM controller (PMIC) with a built-in dual low-side MOSFET gate driver. It simplifies the design of a highly efficient, 2-phase, output buck converter power supply.

The simple control interface, integrated circuit of the NCV7520FPR2G, with its low component count and low component cost, makes this part an ideal fit for cost sensitive system designs. It is well suited for applications requiring its two-phase, two-level power output, including power over Ethernet (PoE) type applications and those with reduced power and noise requirements.

This PMIC includes a few of features such as a wide input voltage range of up to 45V, adjustable Mode Control Pin (MCP) with external components, and a type selectable MCP output source that can be used to adjust the operating frequency and duty cycle of the converter. The PMIC supports an output current up to 5A, and it is available in a small 9-pin SOIC package. The NCV7520FPR2G also provides a thermal shutdown to help protect against overloads.

The NCV7520FPR2G also features a unique floating ground pin that allows for additional flexibility and efficiencies. This pin can be used to tie the positive and negative sides of the DC/DC converter together to reduce losses. This combined with the additional features makes the NCV7520FPR2G a robust solution for many applications.

The NCV7520FPR2G is a great fit for a variety of applications, including: computer systems, office equipment, automotive accessories and communications systems. It is well suited for applications requiring its two-phase, two-level power output, including power over Ethernet (PoE) type applications and those with reduced power and noise requirements.

The NCV7520FPR2G has one main input pin and four output pins. The main input pin receives the voltage from the power supply, while the four output pins are connected to the MOSFET gates that drive the two-phase power output. The output pins are P_COM, N_COM, P and N, which control the voltage and current of the two phases of the on-chip MOSFETs.

The controller uses a current-mode control technique to provide a smooth, reliable control of the two output phases. The voltage from the power supply is fed to the main input pin and is then filtered and fed to the two phases of the two-level MOSFETs. These two sets of MOSFETs work together to provide a constant current output. This allows for a stepless current output, which provides a clean, reliable power output.

The NCV7520FPR2G also provides a type selection feature, which allows users to choose either a fixed or variable output source. The fixed source provides a set voltage and frequency, while the variable source allows the user to set the frequency with an external control pin, allowing the user to customize the frequency and power settings.

Overall, the NCV7520FPR2G is a great choice for those looking for an efficient, reliable and cost-effective solution for 2-phase power output. With its wide input voltage range and adjustable Mode Control Pin, this part is well suited for many applications, including power over Ethernet and reduced power and noise requirements.
