SC2544TSTRT Overview


It comes in the 24-TSSOP (0.173, 4.40mm Width) package, which makes switching controller suitable for most applications. For outputs of 2, this dc motor controller is suitable. PMIC packaging is solid with a Tape & Reel (TR) enclosure. There are Transistor Driver dc switching's output (s) that it can handle. This dc control operates at 4.5V~28V and has a 4.5V~28V supply voltage. Work well in dc switchers with a -40°C~150°C TJ. In this switching controller, the switch can be set to 100kHz~300kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. The dcdc regulator features Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start for efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. The switching converters's terminals (s) are designed at DUAL. A variety of dc switching's functions can be performed on 24 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. It is inputted with a DC switcher's voltage of 16V. You can find other relevant dc to dc converter ics by searching "SC2544". 24 pins are on switching converter. Switching converter is a special type of Switching Regulator or Controllers. The minimum input voltage of the dc dc voltage regulator should 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. If the user wishes to run the voltage regulator dc to dc in a circuit safely and reliably, they should apply 28V. A maximum value of 0.5A is output for current. Having a current greater than 14mA may result in improper operation and possibly damage to the component.
