UC3845DTRG4 Overview
Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. 1 outputs can be generated with the dc motor controller. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. The system can process Transistor Driver dc switching's outputs (s). A 12V~28V voltage is supplied to the dc control and used for operating it. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. Switching can be done at 500kHz with this switching controller. dc dc regulators can be carried out with Surface Mount. DCDC regulator is controlled efficiently by Frequency Control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. The switching converters's terminal (s) are designed at DUAL . Different dc switching's functions can be applied to 14 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. 15V nominal DC switcher's voltage input. Other relevant dc to dc converter ics will be returned if you search "UC3845". There are a total of 14 pins on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. Statistically, DC regulator outputs 13.5V volts. The dc dc regulator's usual output current is 200mA, which should be noted down when you start a project. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. Switching controller operates at 450kHz Hz. 25V is the nominal working voltage. It is important that the controller is supplied with 25mA more than 25mA volts of current.
