DESCRIPTION
The ZCC6501 is a monolithic oscillator/power-driver,
specifically designed for small form factor, isolated power
supplies in isolated interface applications. It drives a
low-profile, center-tapped transformer primary from a 3.3 V
or 5 V DC power supply. The secondary can be wound to provide any isolated voltage based on transformer
turns ratio.
The ZCC6501 consists of an oscillator
followed by a gate drive circuit
that provides the complementary output
signals to drive the ground referenced
N-channel power switches. The
internal logic ensures break-before-make
action between the two switches.
The ZCC6501is available in a small SOT23-5 package, and is specified for operation at temperatures from –40°C
to 125°C.
