MAX1844EEP Overview


Capsuled in the 20-SSOP (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. 1 outputs are supported by the dc motor controller. There is a Tube solid enclosure around the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. 4.5V~5.5V is the supply voltage and the operating voltage of the dc control. Workable in an dc switcher where -40°C~85°C TA is the -40°C~85°C TArm. Using this switching controller, it is possible to switch at 200kHz 300kHz 450kHz 600kHz. The Surface Mount value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Current Limit, Enable, On Time Control, Power Good. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. A switching converters's terminal (s) sits at the DUAL position. An array of 20 terminations of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input is 5V. The minimum input voltage of the dc dc voltage regulator should be 4.5V. This dc to dc regulator accepts only 5.5V input voltage at most. DC to DC voltage regulator has the value of CAN ALSO OPERATE IN PFM MODE to better satisfy the requirement.
