NXF6505-Q100
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.
