SC2544MLTRT Product Details
SC2544MLTRT Overview
As a result of 24-VFQFN Exposed Pad compact design, the switching controller is compatible with most applications. 2 outputs are supported by the dc motor controller. An enclosure of Tape & Reel (TR) is used to package the PMIC. The system can process Transistor Driver dc switching's outputs (s). 4.5V~28V is the supply voltage and the operating voltage of the dc control. Workable in an dc switcher where -40°C~150°C TJ is the -40°C~150°C TJrm. The switching controller is capable of switching at the 100kHz~300kHz position. dc dc regulator can be generalized using Surface Mount. Switching control is made easier with the dcdc regulator's Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start. 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 QUAD. There are many different types of terminations for 24. 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 16V. A search for "SC2544" will reveal other relevant dc to dc converter ics. 24 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. The maximum duty cycle of this voltage regulator dc to dc is set to 90 % to ensure reliability during power-up and power-down. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. DC regulators have a maximum frequency of 300kHz. A circuit should contain 28V in order to ensure the voltage regulator dc to dc runs safely and reliably. The output of this function is the greatest value of 0.5A. There is a possibility that a current higher than 14mA will cause improper operation of the component and possibly damage switching voltage regulators.
