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
' H- s% L# Z/ N0 @+ kor 5 V DC power supply. The secondary can be wound to provide any isolated voltage based on transformer
" R$ u$ A+ {/ Bturns 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.
