SC2544TSTRT Product Details
SC2544TSTRT Overview
It comes in the 24-TSSOP (0.173, 4.40mm Width) package, which makes switching controller suitable for most applications. It is sufficient to generate 2 outputs with this dc motor controller. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 4.5V~28V. Qualified to work in an dc switcher with -40°C~150°C TJ. The switching controller can be switched at 100kHz~300kHz. dc dc regulators can be carried out with Surface Mount. Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start provides dcdc regulator efficient switching control. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. There are a DUAL terminal on the switching converters. Different dc switching's functions can be applied to 24 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input of 16V. SC2544 can be searched for other relevant dc to dc converter ics. In total, switching converter has 24 pins. Switching converter type is specifically Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 4.5V. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 90 %. For safe and reliable operation in a circuit, voltage regulator dc to dc is suggested that users apply 28V. 0.5A is the greatest value switching converter outputs as current. Components may be damaged if their current is greater than 14mA.
