LTC3789IUFD#PBF Product Details

LTC3789IUFD#PBF Overview


It comes in the 28-WFQFN Exposed Pad package, which makes switching controller suitable for most applications. It is sufficient to generate 2 outputs with this dc motor controller. Packaging for the pmic consists of Tube solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 4V~38V. Qualified to work in an dc switcher with -40°C~125°C TJ. The switching controller can be switched at 200kHz~640kHz. dc dc regulators can be carried out with Surface Mount. Current Limit, Enable, Frequency Control, Power Good, Soft Start provides dcdc regulator efficient switching control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a QUAD terminal on the switching converters. Different dc switching's functions can be applied to 28 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. LTC3789 can be searched for other relevant dc to dc converter ics. In total, switching converter has 28 pins. Switching converter type is specifically Switching Regulator or Controllers. Statistically, DC regulator outputs 38V volts. In most cases, the output current of the dc dc regulator will be 20A, so note that when you start the project. 710kHz is the maximum frequency of this dc regulators. For better satisfaction, the value of DC to DC voltage regulator is ALSO OPERATES IN ADJUSTABLE MODE FROM 0.8V TO 38V. The maximum input voltage of the dc switcher is 38V, so users need to limit the voltage accordingly. 4V is the required supply voltage. In this case, the dc switcher won't produce more than 5A watts of output current. At its maximum output, the switching converter can provide 38V volts. Neither the voltage controller's lowest voltage output 800mVr its highest voltage output is less than 800mV.
