TL2845DR-8 Overview

In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. dc motor controller is suitable for 1 output generation. There is a Cut Tape (CT) solid enclosure around the pmic. There are Transistor Driver dc switching's output (s) that it can handle. This dc control operates at 7.6V~30V and has a 7.6V~30V supply voltage. Worked in an dc switcher with a -40°C~85°C TA rating. There is a switch at Up to 500kHz that can be used with this controller. It is suitable for general dc dc regulator when it is set to Surface Mount. For efficient switching control, the dcdc regulator features Frequency Control. An analog IC SWITCHING REGULATOR is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . 8 terminations with various dc switching's functions. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. Searching "TL2845" will return other relevant dc to dc converter ics. In total, switching converter has 8 pins. 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 output current of the dc dc regulator will be 200mA, so note that when you start the project. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 50 % during power-up and power-down. Switching controller operates at 500kHz Hz. As long as the dc switching is in a dormant state, it utilizes 11mA. For nominal working status, the input voltage can be set as 5.5V. There is a requirement for a 15V supply voltage. There should be 30mA current exceeding 30mA supplied to the controller.
