DESCRIPTION
The ZCC6601 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 ZCC6601 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 ZCC6601 is available in a small SOT23-5 package, and is specified for operation at temperatures from –
40°C to 125°C
