适用于隔离式电源的变压器驱动器ZCC6601 替代SN6505

适用于隔离式电源的变压器驱动器ZCC6601 替代SN6505DESCRIPTIONTheZCC6601 is a monolithic oscillator/power-driver, specifically designed forsmall form factor, isolated power supplies in isolated interface applications.It drives a low-profile, center-tapped transformer primary from a 3.3 Vor 5 VDC power supply. The secondary can be wound to provide any isolated voltagebased on transformerturns ratio.TheZCC6601 consists of an oscillator followed by a gate drive circuit thatprovides the complementary output signals to drive the ground referencedN-channel power switches. The internal logic ensures break-before-make actionbetween the two switches.TheZCC6601 is available in a small SOT23-5 package, and is specified for operationat temperatures from –40°C to 125°C.
