Description

UC3846DW Overview
This switching controller fits most application requirements since it is packaged in a 16-SOIC (0.295, 7.50mm Width) package. This dc motor controller can be used to generate outputs with 2 numbers. PMIC is packaged in a solid enclosure of Tube. A total of Transistor Driver dc switching's outputs can be handled by it. A 6.95V~40V voltage is supplied to the dc control and used for operating it. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. Switching can be done at 500kHz with this switching controller. dc dc regulator is made easier with Surface Mount. Current Limit, Enable, Frequency Control, Soft Start provides dcdc regulator efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. There are a DUAL terminal on the switching converters. 16 terminations with various dc switching's functions. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. A search for "UC3846" will reveal other relevant dc to dc converter ics. Total pins of switching converter are 16. There is a particular type of Switching Regulator or Controllers in switching converter. Based on the test statistics, DC regulator outputs voltage 5.1V. normally, the dc dc regulator's output current is 500mA, which you should keep in mind when starting a project. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. Switching controller operates at 450kHz Hz. In dormant mode, 17mA is used. It is possible to set the input voltage to 15V for nominal working status.

The UC3823A and UC3823B and the UC3825A andUC3825B family of PWM controllers are improved versions of the standard UC3823 and UC3825 family. Performance enhancements have been made to several of the circuit blocks. Error amplifier gain bandwidth productis 12 MHz, while input offset voltage is 2 mV. Current limit threshold is assured to a tolerance of 5%. Oscillator discharge current is specified at 10 mA for accurate dead time control. Frequency accuracy is improved to 6%. Startup supply current, typically 100 t,A, is ideal for off-line applications. The output drivers are redesigned to actively sink current during UVLO at no expense to the startup current specification. In addition each output is capable of2-A peak currents during transitions.
