MAX1845EEI+ Overview


With a QSOP package, the switching controller is suitable for a wide range of applications. It is sufficient to generate 2 outputs with this dc motor controller. A solid enclosure of Tube surrounds pmic. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. DUAL are the position of the terminal of the switching converters. There are many different types of terminations for 28. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's voltage input of 5V. Total pins of switching converter are 28. Specially, switching converter corresponds to type Switching Regulator or Controllers. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V. Based on the test statistics, DC regulator outputs voltage 5.5V. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. 540kHz is the maximum frequency of this dc regulators. It is suggested that users apply 5.5V to the voltage regulator dc to dc in order to run it safely and reliably in a circuit. Switching converter outputs current to the greatest value of 0.00005A. At -40°C and above, dc regulator should be kept. A temperature of 85°C more than 85°C degrees Celsius should be maintained in the undc regulator. A total of 2 functions are present in the switch converters. We design voltage regulators switchings with 28 pins. A supply current of 1.1mA is used to power it. The phase of this controller is 1. The frequency at which this controller can perform well is 540kHz.
