MIC3808/3809 www.DataSheet4U.com MIC3808/3809 Micrel Push-Pull PWM Controller General Description The MIC3808 and MIC3809 are a family of complementary output push-pull PWM control ICs that feature high speed and low power consumption. The MIC3808/9 are ideal for telecom level (36V 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 MIC3808/9 allows more efficient utilization of the transformer than singleended 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.
