UC2844BDR2 Overview
This switching controller fits most application requirements since it is packaged in a 14-SOIC (0.154, 3.90mm Width) package. It is sufficient to generate 1 outputs with this dc motor controller. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. Transistor Driver dc switching's outputs (s) are supported. Voltages 10V~36V are the dc control's supply voltage and operating voltage, respectively. A -25°C~85°C TA dc switcher is not a problem. This switching controller can switch at Up to 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Frequency Control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . A variety of terminations with 14 of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. You can find other relevant dc to dc converter ics by searching "UC284*B". Switching converter has a total of 8 pins. Specifically, switching converter falls under the Switching Regulator or Controllers category. DC regulator outputs 5.05V voltage according to the test statistics. The dc to dc regulator can only accept a maximum input voltage of 25V. In most cases, the dc dc regulator's output current is 1A. This information should be noted when you begin working with the component. Voltage regulator dc to dc is designed to operate at 48 % duty cycle during power-ups and power-downs to ensure reliability. In most applications and prototype designs, DC switcher is qualified as a Surface Mount.
