Description
UCC38C44DGKR Overview
Capsuled in the 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) package, the switching controller can be used for a wide range of applications. It is sufficient to generate 1 outputs with this dc motor controller. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. With this function, you can deal with Transistor Driver dc switching's outputs (s). 9V~18V is the supply voltage and the operating voltage of the dc control. Worked in a 0°C~70°C TJ dc switcher before. The switching controller can be switched at Up to 1MHz. A generalization of dc dc regulator can be made using Surface Mount. To ensure efficient switching, this dcdc regulator features a Frequency Control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . 8 terminations with various dc switching's functions. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. In addition to "UCC38C44", there are other relevant dc to dc converter ics you can find. Switching converter has a total of 8 pins. The type is a particular Switching Regulator or Controllers of switching converter. Test statistics indicate DC regulator outputs 18V voltage. You should note that the dc dc regulator's usual output current is 200mA. Voltage regulator dc to dc is designed to operate at 50 % duty cycle during power-ups and power-downs to ensure reliability. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. Switching controllers work at 1MHz Hz. In order to satisfy the need, DC to DC voltage regulator has a value of ALSO OPERATES IN CURRENT MODE. A nominal working status is achieved when the input voltage is set to 18V.
