MIC3808/3809  
Push-Pull PWM Controller  
General Description  
Features  
The MIC3808 and MIC3809 are a family of complementary  
outputpush-pullPWMcontrolICsthatfeaturehighspeedand  
lowpowerconsumption.TheMIC3808/9areidealfortelecom  
level (36V to 75V) isolated step down dc/dc conversion  
applications where high output current, small size, and high  
efficiency are required.  
• Dual output drive stages in push-pull configuration  
• Leading edge current-sense blanking  
• 130µA typical start-up current  
• 1mA typical run current  
• Operation to 1MHz  
• Internal soft start  
• On-chip error amplifier with 4MHz gain bandwidth  
product  
The dual-ended push-pull architecture of the MIC3808/9  
allowsmoreefficientutilizationofthetransformerthansingle-  
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 60ns to  
200ns,limitingthedutycycleofeachoutputstagetolessthan  
50%.  
• On-chip V clamping  
DD  
• Output drive stages capable of 500mA peak source  
current, 1A peak sink current  
Applications  
• High efficiency “brick” power supply modules  
• Half bridge converters  
• Full bridge converters  
TheMIC3808/9arebuiltonalow-power,high-speedBiCMOS  
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. The high-speed internal 4MHz  
error amplifier allows MIC3808/9 operation up to 1MHz.  
• Push-pull converters  
• Voltage-fed push-pull converters  
• Telecom equipment and power supplies  
• Networking power supplies  
• Industrial power supplies  
The MIC3808 has a turn-on threshold of 12.5V whereas the  
MIC3809 has a lower turn-on threshold of 4.3V. Both devices  
are available in SOP-8 and MSOP-8 package options with an  
operating range of –40°C to +85°C.  
• 42V automotive power supplies  
• Base stations
