Описание

The MIC3809YM is a push-pull PWM Controller features high speed and low power consumption. It is ideal for telecom level (36 to 75V) isolated step down dc/dc conversion applications where high output current, small size and high efficiency are required. The dual-ended push-pull architecture of the controller allows more efficient utilization of the transformer than single ended topologies, allowing smaller size dc/dc solutions. Additionally, the out-of-phase push-pull topology allows a higher effective duty cycle, reducing input and output ripple as well as stress on the external components. The dead-time between the two outputs is adjustable between 60 to 200ns, limiting the duty cycle of each output stage to less than 50%. It is built on a low-power, high-speed BiCMOS process. The 130µA start-up current and 1mA run-current reduce the size of the start-up circuitry and allow high efficiency even at light loads.
