TL2845D Overview


Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. There is sufficient capacity to generate switching controller for outputs 1. An enclosure of Tube is used to package the PMIC. The system can process Transistor Driver dc switching's outputs (s). A 7.6V~30V voltage is supplied to the dc control and used for operating it. Workable in an dc switcher where -40°C~85°C TA is the -40°C~85°C TArm. This switching controller can switch at Up to 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. Frequency Control provides dcdc regulator efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING REGULATOR. DUAL are the position of the terminal of the switching converters. A variety of dc switching's functions can be performed on 14 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. Search for "TL2845" to find other relevant dc to dc converter ics. There are 14 pins on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 30V voltage based on test statistics. You should note that the dc dc regulator's usual output current is 200mA. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 48 %. Switching controllers operate at 500kHz frequencies. A nominal working status is achieved when the input voltage is set to 5.5V. This voltage controller requires a supply voltage of 15V. Current supplied to the controller should not exceed 30mA.
