MAX1845EEI Overview
Capsuled in the 28-SSOP (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. This dc motor controller can be used to generate outputs with 2 numbers. PMIC packaging is solid with a Tube enclosure. The system can process Transistor Driver dc switching's outputs (s). Voltages 4.5V~5.5V are the dc control's supply voltage and operating voltage, respectively. Suitable for working in an dc switcher that has a -40°C~85°C TA. With this switching controller, you can switch at 200kHz 300kHz 420kHz 540kHz. The Surface Mount makes it ideal for general dc dc regulator. Switching control is made easier with the dcdc regulator's Current Limit, Enable, On Time Control, Power Good. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. DUAL are the position of the terminal of the switching converters. The 28 terminations can be used for a wide range of dc switching. 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. Other relevant dc to dc converter ics will be returned if you search "MAX1845". Switching converter is a type of Switching Regulator or Controllers in particular. Input voltage of dc dc voltage regulator must be 4.5V. This dc to dc regulator accepts only 5.5V input voltage at most. Whenever the current value is 0.00005A, switching converter outputs the highest possible value.
