LTC3859ALIFE Product Details
LTC3859ALIFE Overview
In the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller meets most application requirements. 3 outputs can be generated with the dc motor controller. PMIC packaging is solid with a Tube enclosure. It is capable of handling Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 4.5V~38V. Worked in a -40°C~125°C TJ dc switcher before. The switching controller is capable of switching at the 115kHz~835kHz 350kHz~535kHz position. Surface Mount makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Enable, Frequency Control, Power Good, Soft Start, Tracking which allows efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Terminal (s) of the switching converters are designed at the DUAL position. There are many different types of terminations for 38. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input of 12V. In addition to "LTC3859", there are other relevant dc to dc converter ics you can find. Switching converter is a type of Switching Regulator or Controllers in particular. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V.
