RT6543BGQW Overview
It comes in a 20-WFQFN Exposed Pad package, so switching controller can be used for most applications. This dc motor controller can be used to generate outputs with 1 numbers. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with 3V ~ 24V voltage are supplied and operated. A -40°C ~ 125°C (TJ) dc switcher is not a problem. A switching controller such as this can switch at a value of 400kHz, 600kHz, 800kHz . It is suitable for general dc dc regulator when it is set to Surface Mount. DCDC regulator is controlled efficiently by Current Limit, Dead Time Control, Enable, Frequency Control, Phase Control, Power Good, Soft Start. As determined by the test statistics, the output voltage of DC regulator is Programmable. You should note down the dc dc regulator's usual output current of - when you start a project. - is a series of dc to dc voltage regulator. Its supplier dc dc controller package would be 20-WQFN (3x3). Adjustable is the frequency at which this controller performs well most of the time.
