General Description
The MIC3838 and MIC3839 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.

Features
• Dual output drive stages in push-pull configuration
• Configurable for current-mode or voltage-mode control
• Easily implements volt-second clamp
• Leading edge current-sense blanking
• 3V reference output available
• 130µA typical start-up current
• 1mA typical run current
• Operation to 1MHz
• On-chip error amplifier with 4MHz gain bandwidth product
• Internal soft start
• On-chip VDD clamping
• Output drive stages capable of 500mA peak source current, 1A peak sink current
