TL3845BDR-8 Overview
The switching controller fits in the 8-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. It is sufficient to generate 1 outputs with this dc motor controller. Tape & Reel (TR) solid enclosure protects the pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching's7.6V~30V is the supply voltage and the operating voltage of the dc control. Worked in an dc switcher with a 0°C~70°C TA rating. There is a switch at 100kHz that can be used with this controller. The Surface Mount makes it ideal for general dc dc regulator. DCDC regulator is controlled efficiently by Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Switching converters are designed with the terminal (s) at position DUAL . A variety of 8 terminations are available in dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. In addition to "TL3845", there are other relevant dc to dc converter ics you can find. Total pins of switching converter are 8. In particular, switching converter belongs to the Switching Regulator or Controllers family. Test statistics indicate DC regulator outputs 30V voltage. You should note down the dc dc regulator's usual output current of 200mA when you start a project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 50 %. Switching controller operates at 500kHz Hz. Input voltage can be set to 5.5V for nominal working status. Voltage 15V must be supplied. There should be 30mA current exceeding 30mA supplied to the controller.
