Product Summary
The LTC3723EGN-1#TR is a synchronous push-pull PWM controller. The LTC3723EGN-1#TR provides all of the control and protection functions necessary for compact and highly efficient, isolated power converters. High integration minimizes external component count, while preserving design flexibility. The robust push-pull output stages switch at half the oscillator frequency. Dead-time is independently programmed with an external resistor. Synchronous rectifier timing is adjustable to optimize efficiency. The applications of the LTC3723EGN-1#TR are (1)telecommunications, infrastructure power systems; (2)distributed power architectures.
