MAX1845EEI Overview


With a 28-SSOP (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. It is sufficient to generate 2 outputs with this dc motor controller. An enclosure of Tube is used to package the PMIC. Transistor Driver dc switching's outputs (s) are supported. The supply and operating voltage of the dc control are 4.5V~5.5V. A -40°C~85°C TA dc switcher is not a problem. Switching can be done at 200kHz 300kHz 420kHz 540kHz with this switching controller. A generalization of dc dc regulator can be made using Surface Mount. 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 DUAL SWITCHING CONTROLLER analog outputs. switching converters terminal (s) are designed to be at DUAL. Different dc switching's functions can be applied to 28 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 5V. This dc dc voltage regulator should be powered by a voltage of 4.5V. Voltages 5.5V are the maximum that the dc to dc regulator will accept.
