LTC3899HUHF#TRPBF Product Details
LTC3899HUHF#TRPBF Overview
This switching controller fits most application requirements since it is packaged in a 38-WFQFN Exposed Pad package. There is enough capacity in the dc motor controller to generate the output for the 3 input. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. It is capable of handling Transistor Driver dc switching's outputs (s). 4.5V~60V is the supply voltage and the operating voltage of the dc control. Qualified to work in a -40°C~150°C TJ dc switcher. Switching can be done at 105kHz~835kHz 350kHz~535kHz with this switching controller. The Surface Mount allows it to be used for dc dc regulator in general. Enable, Frequency Control, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. In addition to "LTC3899", there are other relevant dc to dc converter ics you can find. Pins number 38 of switching converter in total. voltage regulator dc to dcs with a 100 % duty cycle are designed to be reliable when powered on and powered off.
