UC2845BDR2 Overview
The switching controller fits in the 14-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. For 1 outputs, the dc motor controller is appropriate. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. Transistor Driver dc switching's outputs (s) are supported. The supply and operating voltage of the dc control are 7.6V~30V. Suitable for a -25°C~85°C TA dc switcher. A switching controller such as this can switch at a value of 500kHz . As it has a Surface Mount value, it can be used for general dc dc regulator. Frequency Control provides dcdc regulator efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . There are many different types of terminations for 14. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. Searching "UC284*B" will return other relevant dc to dc converter ics. There are 14 pins on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. DC regulator outputs 5.05V voltage based on test statistics. Voltages 25V are the maximum that the dc to dc regulator will accept. In most cases, the dc dc regulator's output current is 1A. This information should be noted when you begin working with the component. The maximum duty cycle of this voltage regulator dc to dc is set to 48 % to ensure reliability during power-up and power-down. DC regulator275kHz has the maximum frequency. When running the voltage regulator dc to dc in a circuit, users should apply 30V to ensure safety and reliability.
