UC3843BD1013TR Overview

In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 1. A solid enclosure of Tape & Reel (TR) surrounds pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sDC control operates at 7.6V~30V volts and has 7.6V~30V supply voltage. Qualified to work in an dc switcher with 0°C~70°C TJ. In this switching controller, the switch can be set to Up to 500kHz. dc dc regulator is made easier with Surface Mount. DCDC regulator is controlled efficiently by Frequency Control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. 8 terminations with a variety of function. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. A DC switcher's nominal voltage of 15V is input. Searching "UC3843" will return other relevant dc to dc converter ics. Pins number 8 of switching converter in total. There is a particular type of Switching Regulator or Controllers in switching converter. Based on the test statistics, DC regulator outputs voltage 5.1V. The dc to dc regulator can only accept a maximum input voltage of 30V. The dc dc regulator's usual output current is 1A, which should be noted down when you start a project. The maximum duty cycle of this voltage regulator dc to dc is set to 100 % to ensure reliability during power-up and power-down. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. Switching controller operates at 500kHz Hz. DC switching uses 12mA when it is dormant. There is a possibility that a current higher than 17mA will cause improper operation of the component and possibly damage switching voltage regulators.
