UC2844AQD8 Product Details
UC2844AQD8 Overview
The switching controller fits in the 8-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. This dc motor controller can be used to generate outputs with 1 numbers. Packaging for the pmic consists of Tube solid enclosures. It is capable of handling Transistor Driver dc switching's outputs (s). A 10V~30V voltage is supplied to the dc control and used for operating it. Work well in dc switchers with a -40°C~125°C TA. A switching controller such as this can switch at a value of Up to 500kHz . The Surface Mount makes it ideal for general dc dc regulator. Frequency Control is used for efficient switching control in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. Various 8 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. Other relevant dc to dc converter ics can be found by searching "UC2844". 8 pins are present on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. A 15V voltage of DC regulator was detected in the test statistics. It should be fully noted that the dc to dc regulator only accepts 25V input voltage at most. 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. Switching controllers work at 450kHz Hz. Dormant dc switchings use 11mA. Voltage 11V is required for supply. The controller should not be supplied with more current than 25mA.
