TL2844D Overview
In the 14-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 1. PMIC packaging is solid with a Tube enclosure. There are Transistor Driver dc switching's output (s) that it can handle. 10V~30V is the operating voltage and supply voltage of the dc control. Suitable for work in a -40°C~85°C TA dc switcher. Switching can be done at Up to 500kHz with this switching 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. A SWITCHING REGULATOR analog integrated circuit is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. A variety of terminations with 14 of dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Searching "TL2844" will return other relevant dc to dc converter ics. 14 pins are present on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. Statistically, DC regulator outputs 30V volts. In most cases, the dc dc regulator's output current is 200mA. This information should be noted when you begin working with the component. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. 500kHz is the frequency of the switching controller. It is possible to set the input voltage to 5.5V for nominal working status. Switching controller is necessary to provide a voltage of 15V. There should be 30mA more than 30mA amps of current supplied to the controller.
