UC3842ADX Overview
In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. It is sufficient to generate 1 outputs with this dc motor controller. PMIC packaging is solid with a Tape & Reel (TR) enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sDC control operates at 10V~30V volts and has 10V~30V supply voltage. Suitable for working in an dc switcher that has a 0°C~70°C TA. A switching controller such as this can switch at a value of Up to 500kHz . dc dc regulators can be carried out with Surface Mount. DCDC regulator is controlled efficiently by Frequency Control. Search for "UC3842" to find other relevant dc to dc converter ics. There are 8 pins on switching converter. In most cases, the output current of the dc dc regulator will be 1A, so note that when you start the project. The duty cycle of the voltage regulator dc to dc can be set to 100 % on power-up or power-down to ensure reliability. This Surface Mount makes DC switcher suitable for most prototypes and applications. There is 17mA supply current for it. There is 17mA nominal current supply for this the controllers dc.
