LTC3890IGN-1#PBF Product Details
LTC3890IGN-1#PBF Overview
As a result of 28-SSOP (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. 2 outputs are supported by the dc motor controller. An enclosure of Tube is used to package the PMIC. The system can process Transistor Driver dc switching's outputs (s). 4V~60V is the supply voltage and the operating voltage of the dc control. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. The switching controller is capable of switching at the 105kHz~835kHz 350kHz~535kHz position. dc dc regulator can be generalized using Surface Mount. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Power Good, Soft Start, Tracking. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. switching converters terminal (s) are designed to be at DUAL. There are many different types of terminations for 28. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 12V. A search for "LTC3890" will reveal other relevant dc to dc converter ics. 28 pins are present on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. Input voltage of dc dc voltage regulator must be 4V. Statistically, the DC regulator outputs 24V voltage. Voltages 60V are the maximum that the dc to dc regulator will accept. DC regulators have a maximum frequency of 850kHz. Channels 1 are required for high-quality communication.
