NXF6501DC-Q100

Low-noise, 1.2 A transformer driver for isolated power supplies

The NXF6501-Q100 is a specialized push-pull transformer driver that is designed for isolated power supplies in small form factors. This driver is capable of driving low-profile, center-tapped transformers from a 2.25 V to 5.5 V DC power supply, while achieving ultra-low noise and EMI using slew rate control and Spread Spectrum Clocking (SSC).

The NXF6501-Q100 includes internal protection features such as current limiting, undervoltage lockout, thermal shutdown, and break-before-make circuitry, ensuring the device maintains safe limits. The device also includes a soft-start feature that prevents high inrush current during power-up with large load capacitors.

The NXF6501-Q100 is constructed using an oscillator and a gate drive circuit that produces complementary output signals to drive ground-referenced N-channel power switches. These two complementary 1.2 A power-MOSFET switches can be used to provide >6 W power.

The NXF6501-Q100 410 kHz internal oscillator is for applications that require higher efficiency and smaller transformers. The NXF6501-Q100 is available in a small 5 pin SOT8098-1 package and is characterized for operation within a temperature range of -55 °C to 125 °C.

This product has been qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1) and is suitable for use in automotive applications.

Sample

As a Nexperia customer you can order samples via our sales organization.

If you do not have a direct account with Nexperia our network of global and regional distributors is available and equipped to support you with Nexperia samples. Check out the list of official distributors.

How does it work?

The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
