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 plementary output signals to drive the ground referenced N-channel power switches. The internal logic ensures break-before-make action between the two switches. The ZCC6501 is available in a small SOT23-5 package, and is specified for operation at temperatures from - 40°C to 125°C.

Typical Operating Circuit These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. FUNCTIONAL BLOCK...
