TL2845DR Overview
Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. The dc motor controller is adquate to generate for 1 outputs. A solid enclosure of Tape & Reel (TR) surrounds pmic. Transistor Driver dc switching's outputs (s) can be handled by it. Voltages 7.6V~30V are the dc control's supply voltage and operating voltage, respectively. Work well in dc switchers with a -40°C~85°C TA. It 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. The switch converters are connected to a SWITCHING REGULATOR analog IC. Terminal (s) of the switching converters are designed at the DUAL position. A variety of 14 terminations are available in dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. A search for "TL2845" will reveal other relevant dc to dc converter ics. There are only 14 pins on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. Based on the test statistics, DC regulator outputs voltage 30V. In most cases, the dc dc regulator's output current is 200mA. This information should be noted when you begin working with the component. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 48 %. There is 500kHz frequency setting on the switching controller. It is possible to set the input voltage to 5.5V for nominal working status. Switching controller is necessary to provide a voltage of 15V. It is not recommended to supply more current to the controller than 30mA.
