DESCRIPTION
The PC 6 5 0 5 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 3V to12 V DC power supply. The secondary can be wound to provide any is
olated voltage based on transformer turns ratio.
The PC6505 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 enable pin can on
or off output.
The PC6505 is available in a small SOT23-5 package, and is specified for operation at
temperatures from 鈥�40掳C to 125掳C.
