MIC3838YMM

The MIC3838/39 are a family of complementary output push-pull PWM control ICs that feature high speed and low power consumption. The MIC3838/9 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 MIC3838/9 are designed for high flexibility with minimum pin-count. Additionally, the MIC3838/9 can easily implement a volt-second clamp that automatically limits the duty cycle during input transients. A 3V reference output is also available that eliminates the need for an external reference. The dual-ended push-pull architecture of the MIC3838/9 allows more efficient utilization of the transformer than single-ended Additionally, the out-of-phase push-pull topology allows a higher effective duty cycle, reducing The dead-time between the two outputs is adjustable between 60ns to 200ns, limiting The dead-time between the two outputs is adjustable between 60ns to 200ns, limiting the duty cycle of each output stage to less than 50%. The MIC3838 has a turn-on threshold of 12.5V whereas the MIC3839 has a lower turn-on threshold of 4.3V. Both devices are available in a small size MSOP-10 Both devices are available in a small size MSOP-10 package with an operating range of -40°C to +85°C.
