UC3844AD8TRG4 Product Details
UC3844AD8TRG4 Overview
As a result of 8-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. 1 outputs are supported by the dc motor controller. An enclosure of Tape & Reel (TR) is used to package the PMIC. The system can process Transistor Driver dc switching's outputs (s). 10V~30V is the supply voltage and the operating voltage of the dc control. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. The switching controller is capable of switching at the Up to 500kHz position. dc dc regulator can be generalized using Surface Mount. Switching control is made easier with the dcdc regulator's Frequency Control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. switching converters terminal (s) are designed to be at DUAL. There are many different types of terminations for 8. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. A search for "UC3844" will reveal other relevant dc to dc converter ics. 8 pins are present on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. Statistically, the DC regulator outputs 15V voltage. 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 maximum duty cycle of this voltage regulator dc to dc is set to 50 % to ensure reliability during power-up and power-down. Switching controller operates at 450kHz Hz. It is possible to set the input voltage as 25V for nominal working statuses. The supply voltage should be 11V.
