MAX1845EEI+ Product Details

MAX1845EEI+ Overview


As a result of QSOP compact design, the switching controller is compatible with most applications. 2 outputs are supported by the dc motor controller. An enclosure of Tube is used to package the PMIC. Connected to a DUAL SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. switching converters terminal (s) are designed to be at DUAL. There are many different types of terminations for 28. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 5V. 28 pins are present on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. Input voltage of dc dc voltage regulator must be 4.5V. Statistically, the DC regulator outputs 5.5V voltage. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. DC regulators have a maximum frequency of 540kHz. A circuit should contain 5.5V in order to ensure the voltage regulator dc to dc runs safely and reliably. The output of this function is the greatest value of 0.00005A. A temperature -40°C lower than -40°C should be maintained. A temperature of 85°C more than 85°C degrees Celsius should be maintained in the undc regulator. In total, thare switch converters have 2 functions. A voltage regulators switching with 28 pins is designed. The supply current of the voltage controller is 1.1mA. With this controller, the phase is 1. The frequency at which this controller generally works well is 540kHz.
