LTC3891IFE#PBF Overview
The switching controller fits in the 20-TSSOP (0.173, 4.40mm Width) Exposed Pad package and is ideal for most applications. This dc motor controller can be used to generate outputs with 1 numbers. The pmic is packaged in Tube solid enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sdc control's supply and operating voltages are 4V~60V. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. A switching controller such as this can switch at a value of 105kHz~835kHz 350kHz~535kHz . dc dc regulator can be generalized using Surface Mount. For efficient switching control, the dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. There are a DUAL terminal on the switching converters. Various 20 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 12V. A search for "LTC3891" will reveal other relevant dc to dc converter ics. Pins number 20 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. An input voltage of 4V is the minimum required for the dc dc voltage regulator. A 24V voltage of DC regulator was detected in the test statistics. A maximum voltage of 60V is accepted by the dc to dc regulator as an input voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 5A. This dc regulatorhas a max frequency of 835kHz. The value of DC to DC voltage regulator is set to ALSO OPERATES IN ADJUSTABLE MODE FROM 0.80V TO 24V in order to better satisfy the requirement.
