LTC3721EGN-1#PBF

LTC3721-1 is a push-pull PWM controller 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. 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 features extremely low operating and start-up currents and reliable short-circuit and overtemperature protection. It is used in application such as telecommunications, infrastructure power systems, distributed power architectures, server power supplies, high density power modules etc.
