UC3827DWTR-1 Product Details
UC3827DWTR-1 Overview
It comes in the 24-SOIC (0.295, 7.50mm Width) package, which makes switching controller suitable for most applications. It is sufficient to generate 3 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 7.6V~20V. Qualified to work in an dc switcher with 0°C~70°C TA. The switching controller can be switched at 220kHz. dc dc regulators can be carried out with Surface Mount. Frequency Control, Ramp, Soft Start provides dcdc regulator efficient switching control. The switch converters are connected to an analog IC with a 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 15V. UC3827 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. Statistically, DC regulator outputs 2.5V volts. In most cases, the output current of the dc dc regulator will be 100mA, so note that when you start the project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 95 %. 450kHz is the frequency of the switching controller. For better satisfaction, the value of DC to DC voltage regulator is CAN ALSO WORK IN CURRENT MODE. 15V is the nominal working voltage.
