LTC3890HGN-3#PBF Product Details
LTC3890HGN-3#PBF Overview
The switching controller fits in the 28-SSOP (0.154, 3.90mm Width) package and is ideal for most applications. dc motor controller is suitable for 2 output generation. Packaged in solid enclosures, this pmic has a Tube rating. There are Transistor Driver dc switching's output (s) that it can handle. A 4V~60V voltage is supplied to the dc control and used for operating it. Suitable for work in a -40°C~150°C TJ dc switcher. With this switching controller, you can switch at 105kHz~835kHz 350kHz~535kHz. The Surface Mount makes it ideal for general dc dc regulator. Featured in the dcdc regulator is Enable, Frequency Control, Power Good, Soft Start, Tracking which allows efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. There are a terminal (s) on the switching converters that are designed at DUAL. 28 terminations with various dc switching's functions. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 12V. Other relevant dc to dc converter ics will be returned if you search "LTC3890". Total pins of switching converter are 28. Particularly, switching converter is a type of Switching Regulator or Controllers. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. Considering the dc to dc regulator can only accept 60V input voltage, it is important to take note of this. The duty cycle of the voltage regulator dc to dc can be set to 99 % on power-up or power-down to ensure reliability.
