UC2844AD8TRG4 Overview
Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. It is sufficient to generate 1 outputs with this dc motor controller. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. There are Transistor Driver dc switching's output (s) that it can handle. A 10V~30V voltage is supplied to the dc control and used for operating it. Worked in an dc switcher with a -40°C~85°C TA rating. With this switching controller, you can switch at Up to 500kHz. dc dc regulator is made easier with Surface Mount. Frequency Control provides dcdc regulator efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. There are a terminal (s) on the switching converters that are designed at DUAL. An array of 8 terminations of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. In addition to "UC2844", there are other relevant dc to dc converter ics you can find. Total pins of switching converter are 8. Switching converter is a special type of Switching Regulator or Controllers. DC regulator outputs 15V voltage according to the test statistics. You should note that the dc dc regulator's usual output current is 200mA. Voltage regulator dc to dc is designed to operate at 50 % duty cycle during power-ups and power-downs to ensure reliability. A frequency of 450kHz is set for the switching controller. You can set the input voltage to 25V for nominal working status. There must be a voltage supply of 11V volts. You should not supply more current than 25mA to the controller.
