UC2845BD1R2 Overview
The switching controller fits in the 8-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. It is sufficient to generate 1 outputs with this dc motor controller. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. The program can handle Transistor Driver dc switching's outputs (s). dc controls with 7.6V~30V voltage are supplied and operated. Suitable for working in an dc switcher that has a -25°C~85°C TA. In this switching controller, the switch can be set to 500kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. Frequency Control is used for efficient switching control in the dcdc regulator. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. 8 terminations with a variety of function. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. UC284*B can be searched for other relevant dc to dc converter ics. There are 8 pins on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. A 5.05V voltage of DC regulator was detected in the test statistics. The dc to dc regulator can only accept 25V input voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 1A. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 48 %. It is estimated that this dc regulatorhas a maximum frequency of 275kHz. If the user wishes to run the voltage regulator dc to dc in a circuit safely and reliably, they should apply 30V.
