TL2845DG4-8 Overview
As a result of 8-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. This dc motor controller can be used to generate outputs with 1 numbers. A solid enclosure of Tube surrounds pmic. There are Transistor Driver dc switching's output (s) that it can handle. A 7.6V~30V voltage is supplied to the dc control and used for operating it. Worked in an dc switcher with a -40°C~85°C TA rating. Using this switching controller, it is possible to switch at Up to 500kHz. Surface Mount makes it suitable for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. There are a DUAL terminal on the switching converters. 8 terminations with a variety of function. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. Other relevant dc to dc converter ics will be returned if you search "TL2845". Total pins of switching converter are 8. Switching converter is a type of Switching Regulator or Controllers in particular. DC regulator outputs 30V voltage according to the test statistics. If you are starting a new project, you should note the dc dc regulator's typical 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 %. There is 500kHz frequency setting on the switching controller. 5.5V is the nominal working voltage. Switching controller is necessary to provide a voltage of 15V. Current supplied to the controller should not exceed 30mA.
