LTC3721-11sn37211 37211fsAPPLICATIO SUFEATURESTYPICAL APPLICATIOUDESCRIPTIOUThe LTC 3721-1 Push-Pull PWM Controller provides all ofthe control and protection functions necessary for com-pact and highly efficient, isolated power converters. Highintegration minimizes external component count, whilepreserving design robust Push-Pull output stages switch at half theoscillator frequency. Dead-time is independently pro-grammed with an external resistor. A UVLO program inputprovides precise system turn-on and turn off voltages. TheLTC3721-1 features peak current mode control with pro-grammable slope compensation and leading LTC3721-1 features extremely low operating andstart-up currents and reliable short-circuit andovertemperature protection.
