LTC3774EUHE#PBF Overview

As a result of 36-WFQFN Exposed Pad compact design, the switching controller is compatible with most applications. For 2 outputs, the dc motor controller is appropriate. Tube solid enclosure protects the pmic. PWM Signal dc switching's outputs (s) can be handled by it. A 4.5V~38V voltage is supplied to the dc control and used for operating it. Worked in an dc switcher with a -40°C~125°C TJ rating. It can switch at 150kHz~1.2MHz. dc dc regulator can be generalized using Surface Mount. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at QUAD . Different dc switching's functions can be applied to 36 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. Search for "LTC3774" to find other relevant dc to dc converter ics. Switching converter has a total of 36 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 4.5V. The dc to dc regulator can only accept a maximum input voltage of 38V. If you start a project, note down the dc dc regulator's usual output current of 25A. The maximum duty cycle of this voltage regulator dc to dc is set to 98 % to ensure reliability during power-up and power-down. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. To better satisfy the need, DC to DC voltage regulator has a value of OUTPUT VOLTAGE RANGE FROM 0.6 VOLT TO 3.5 VOLT. There are several dc to dc voltage regulator in the PolyPhase? series.
