UC2844ADTRG4 Overview
Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. This dc motor controller can be used to generate outputs with 1 numbers. PMIC packaging is solid with a Tape & Reel (TR) enclosure. With this function, you can deal with Transistor Driver dc switching's outputs (s). 10V~30V is the operating voltage and supply voltage of the dc control. Work well in dc switchers with a -40°C~85°C TA. A switching controller such as this can switch at a value of Up to 500kHz . dc dc regulators can be carried out with Surface Mount. Frequency Control provides dcdc regulator efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. The switching converters's terminals (s) are designed at DUAL. There are many different types of terminations for 14. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. A DC switcher's nominal voltage of 15V is input. Other relevant dc to dc converter ics will be returned if you search "UC2844". 14 pins are on switching converter. In particular, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 15V voltage according to the test statistics. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. The duty cycle of the voltage regulator dc to dc can be set to 50 % on power-up or power-down to ensure reliability. 450kHz is the frequency of the switching controller. It is possible to set the input voltage as 25V for nominal working statuses. Voltage 11V is required for supply.
