UC3827DW-1 Overview
Capsuled in the 24-SOIC (0.295, 7.50mm Width) package, the switching controller can be used for a wide range of applications. For 3 outputs, the dc motor controller is appropriate. PMIC is packaged in a solid enclosure of Tube. Transistor Driver dc switching's outputs (s) are supported. 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. As it has a Surface Mount value, it can be used for general dc dc regulator. The dcdc regulator features Frequency Control, Ramp, Soft Start for efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a DUAL terminal on the switching converters. An array of 24 terminations of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. You can find other relevant dc to dc converter ics by searching "UC3827". 24 pins are present on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. DC regulator outputs 2.5V voltage based on test statistics. If you are starting a new project, you should note the dc dc regulator's typical output current is 100mA. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 95 %. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. Switching controllers work at 450kHz Hz. DC to DC voltage regulator has the value of CAN ALSO WORK IN CURRENT MODE to better satisfy the requirement. It is possible to set the input voltage as 15V for nominal working statuses.
