LTC3728LIUH-1#TRPBF Overview

It comes in the 32-WFQFN Exposed Pad package, which makes switching controller suitable for most applications. 2 outputs can be generated with the dc motor controller. Tape & Reel (TR) solid enclosure protects the pmic. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching's4.5V~35V is the supply voltage and the operating voltage of the dc control. Worked in an dc switcher with a -40°C~85°C TA rating. There is a switch at 260kHz~550kHz that can be used with this controller. dc dc regulator can be generalized using Surface Mount. Enable, Power Good, Soft Start provides dcdc regulator efficient switching control. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. switching converters terminal (s) are designed to be at QUAD. An array of 32 terminations of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. LTC3728 can be searched for other relevant dc to dc converter ics. The switching converter has a total of 32 pins. Specifically, switching converter falls under the Switching Regulator or Controllers category. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator. According to the test statistics, DC regulator outputs 3.35V voltage. The dc dc regulator's usual output current is 3A, which should be noted down when you start a project. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. DC regulators have a maximum frequency of 590kHz. For high-quality communication, there are 1 channels.
