UC3844BD1R2 Overview
With a 8-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. dc motor controller is suitable for 1 output generation. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. It is capable of handling Transistor Driver dc switching's outputs (s). DC control operates at 10V~36V volts and has 10V~36V supply voltage. Qualified to work in an dc switcher with 0°C~70°C TA. The switching controller is capable of switching at the Up to 500kHz position. The Surface Mount makes it ideal for general dc dc regulator. DCDC regulator is controlled efficiently by Frequency Control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . An array of 8 terminations of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. A DC switcher's nominal voltage of 15V is input. You can find other relevant dc to dc converter ics by searching "UC384*B". There are 8 pins on switching converter. Switching converter type is specifically Switching Regulator or Controllers. A 5.1V voltage of DC regulator was detected in the test statistics. The dc to dc regulator is limited to 25V input voltage. In most cases, the output current of the dc dc regulator will be 1A, so note that when you start the project. voltage regulator dc to dcs with a 48 % duty cycle are designed to be reliable when powered on and powered off. Having a Surface Mount makes DC switcher suitable for most application and prototype designs.
