Low-noise, 1.2 A transformer driver for isolated power supplies
The NXF6505A/B-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 NXF6505A/B-Q100 features internal protection features such as current limiting, undervoltage lockout, thermal shutdown, and break-before-make circuitry, ensuring the device operates within safe limits. The device also includes a soft-start feature that prevents high inrush current during power-up with large load.
The NXF6505A/B-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 440 kHz internal oscillator is for applications that require higher efficiency and smaller transformers. The NXF6505A/B-Q100 is available in a small 6 pin SOT8061-1 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.

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.
