Description
UC3844BD1G Overview
Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. 1 outputs can be generated with the dc motor controller. Packaging for the pmic consists of Tube solid enclosures. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 10V~36V and has a 10V~36V supply voltage. Qualified to work in an dc switcher with 0°C~70°C TA. This switching controller can switch at Up to 500kHz. The Surface Mount makes it ideal for general dc dc regulator. For efficient switching control, the dcdc regulator features Frequency Control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. A switching converters's terminal (s) sits at the DUAL position. The 8 terminations can be used for a wide range of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. In addition to "UC384*B", there are other relevant dc to dc converter ics you can find. Pins number 8 of switching converter in total. The type is a particular Switching Regulator or Controllers of switching converter. Test statistics indicate DC regulator outputs 13.4V voltage. Voltages 25V are the maximum that the dc to dc regulator will accept. You should note that the dc dc regulator's usual output current is 200mA. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 48 %. DC switcher's Surface Mount qualifies it for most applications and prototypes. Switching controllers operate at 52kHz frequencies. Having a current greater than 30mA may result in improper operation and possibly damage to the component.
