TL2844DRG4 Overview


This switching controller fits most application requirements since it is packaged in a 14-SOIC (0.154, 3.90mm Width) package. It is sufficient to generate 1 outputs with this dc motor controller. An enclosure of Tape & Reel (TR) is used to package the PMIC. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 10V~30V. Suitable for working in an dc switcher that has a -40°C~85°C TA. This switching controller can switch at Up to 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. For efficient switching control, the dcdc regulator features Frequency Control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. The 14 terminations can be used for a wide range of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. In addition to "TL2844", there are other relevant dc to dc converter ics you can find. There are 14 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 30V. You should note down the dc dc regulator's usual output current of 200mA when you start a project. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. The switching controller works at a frequency of 500kHz. 5.5V is the nominal working voltage. This voltage controller requires a supply voltage of 15V. In order to ensure proper operation, the controller should not receive more current than 30mA.
