MAX1844ETP+T Product Details
MAX1844ETP+T Overview
It comes in a 20-WFQFN Exposed Pad package, so switching controller can be used for most applications. 1 outputs can be generated with the dc motor controller. PMIC is packaged in a solid enclosure of Tape & Reel (TR). There are Transistor Driver dc switching's output (s) that it can handle. A 4.5V~5.5V voltage is supplied to the dc control and used for operating it. A -40°C~85°C TA dc switcher is not a problem. There is a switch at 200kHz 300kHz 450kHz 600kHz that can be used with this controller. As it has a Surface Mount value, it can be used for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, On Time Control, Power Good. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. switching converters terminal (s) are designed to be at QUAD. 20 terminations with a variety of function. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's voltage input is 5V. You can find other relevant dc to dc converter ics by searching "MAX1844". There is a particular type of Switching Regulator or Controllers in switching converter. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V. Voltages 5.5V are the maximum that the dc to dc regulator will accept. The value of DC to DC voltage regulator is set to CAN ALSO OPERATE IN PFM MODE in order to better satisfy the requirement. Whenever the current value is 3A, switching converter outputs the highest possible value.
