LTC3723EGN-1#PBF

LTC3723-1 is a synchronous push-pull PWM controller provide 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. A UVLO program input provides precise system turn-on and turn off voltages. It features peak current mode control with programmable slope compensation and leading edge blanking. It feature extremely low operating and start-up currents. Both devices provide reliable short-circuit and overtemperature protection. It is widely used in application such as telecommunications, infrastructure power systems, distributed power architectures etc.
