TL3843BD Overview
With a 14-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. 1 outputs are supported by the dc motor controller. Packaged in solid enclosures, this pmic has a Tube rating. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching's7.6V~30V is the operating voltage and supply voltage of the dc control. Suitable for working in an dc switcher that has a 0°C~70°C TA. There is a switch at Up to 500kHz that can be used with this controller. The Surface Mount makes it ideal for general dc dc regulator. The dcdc regulator features Frequency Control for efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. 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. There is a DC switcher's nominal voltage of 15V. Other relevant dc to dc converter ics will be returned if you search "TL3843". Total pins of switching converter are 14. The type is a particular Switching Regulator or Controllers of switching converter. DC regulator outputs 30V voltage according to the test statistics. normally, the dc dc regulator's output current is 200mA, which you should keep in mind when starting a project. The duty cycle of the voltage regulator dc to dc can be set to 100 % on power-up or power-down to ensure reliability. A frequency of 500kHz is used by the switching controller. Input voltage can be set to 5.5V for nominal working status. The supply voltage must be 15V. The controller should not be supplied with more current than 30mA.
