MAX1897ETP+ Overview

In the 20-WQFN Exposed Pad package, the switching controller meets most application requirements. This dc motor controller can be used to generate outputs with 1 numbers. Tube solid enclosure protects the pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sDC control operates at 4.5V~5.5V volts and has 4.5V~5.5V supply voltage. A -40°C~85°C TA dc switcher is not a problem. In this switching controller, the switch can be set to 200kHz 300kHz 550kHz. Surface Mount makes it suitable for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, On Time Control. SWITCHING CONTROLLER analog IC connects the switch converters. A switching converters's terminal (s) sits at the QUAD position. A variety of 20 terminations are available in dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. 5V nominal DC switcher's voltage input. MAX1897 can be used to locate other relevant dc to dc converter ics. In total, switching converter has 20 pins. Switching converter type is specifically Switching Regulator or Controllers. 4.5V should be the minimum input voltage for the dc dc voltage regulator. Voltages 5.5V are the maximum that the dc to dc regulator will accept. DC regulators have a maximum frequency of 550kHz. DC to DC voltage regulator has the value of ALSO REQUIRES A BATTERY VOLTAGE OF 4V TO 28V to better satisfy the requirement. The dc to dc voltage regulator is from the Quick-PWM? series.
