UC2844ANG4 Overview


It comes in the 8-DIP (0.300, 7.62mm) package, which makes switching controller suitable for most applications. There is sufficient capacity to generate switching controller for outputs 1. An enclosure of Tube is used to package the PMIC. The program can handle 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. The switching controller is capable of switching at the Up to 500kHz position. The Through Hole value makes it suitable for general dc dc regulator. Frequency Control is used for efficient switching control in the dcdc regulator. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. A switching converters's terminal (s) sits at the DUAL position. 8 terminations with a variety of function. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's input voltageis 15V volts. A search for "UC2844" will reveal other relevant dc to dc converter ics. There are a total of 8 pins on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. DC regulator outputs 15V voltage based on test statistics. In most cases, the dc dc regulator's output current is 200mA. This information should be noted when you begin working with the component. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 50 %. Switching controller operates at a frequency of 500kHz. Input voltage can be set to 25V for nominal working status. There is a requirement for a 11V supply voltage. There should be 25mA more than 25mA amps of current supplied to the controller. 11mA current flow input could be used to operate the switching converter .
