MAX1844EEP Overview
As a result of 20-SSOP (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. Packaged in solid enclosures, this pmic has a Tube rating. It is capable of handling Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 4.5V~5.5V. Workable in an dc switcher where -40°C~85°C TA is the -40°C~85°C TArm. Switching can be done at 200kHz 300kHz 450kHz 600kHz with this switching controller. The Surface Mount value makes it suitable for general dc dc regulator. Current Limit, Enable, On Time Control, Power Good provides dcdc regulator efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. The switching converters's terminals (s) are designed at DUAL. Different dc switching's functions can be applied to 20 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The nominal DC switcher's voltage input is 5V. In addition to "MAX1844", there are other relevant dc to dc converter ics you can find. Switching converter is a special type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 4.5V. The dc to dc regulator can only accept a maximum input voltage of 5.5V. This value is CAN ALSO OPERATE IN PFM MODE so that DC to DC voltage regulator better serves the purpose. Current is output to the greatest value of 3A.
