LTC3890IGN-1#PBF Overview


With a 28-SSOP (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. Packaged in solid enclosures, this pmic has a Tube rating. The program can handle Transistor Driver dc switching's outputs (s). 4V~60V is the operating voltage and supply voltage of the dc control. Suitable for work in a -40°C~125°C TJ dc switcher. The switching controller can be switched at 105kHz~835kHz 350kHz~535kHz. A generalization of dc dc regulator can be made using Surface Mount. The dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking for efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Switching converters are designed with the terminal (s) at position DUAL . The 28 terminations can be used for a wide range of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 12V. In addition to "LTC3890", there are other relevant dc to dc converter ics you can find. There are a total of 28 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. The minimum input voltage of the dc dc voltage regulator should be 4V. Test statistics indicate DC regulator outputs 24V voltage. Voltages 60V are the maximum that the dc to dc regulator will accept. DC regulator's maximum frequency is 850kHz. A high-quality communication requires 1 channels.
