MIC3809YMM

Push-pull PWM controller that feature high speed and low power consumption. It is 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. It is also suitable for use in high efficiency “brick” power supply modules (half bridge converters, Full bridge converters, push-pull converters, voltage-fed push-pull converters), telecom equipment and power supplies, networking power supplies, industrial power supplies, 42V automotive power supplies, base stations.
