LTC3774IUHE#PBF Overview


Capsuled in the 36-WFQFN Exposed Pad package, the switching controller can be used for a wide range of applications. The dc motor controller is adquate to generate for 2 outputs. Tube solid enclosure protects the pmic. It is capable of dealing with PWM Signal dc switching's output (s). dc switching'sDC control operates at 4.5V~38V volts and has 4.5V~38V supply voltage. Qualified to work in a -40°C~125°C TJ dc switcher. A switching controller such as this can switch at a value of 150kHz~1.2MHz . dc dc regulators can be carried out with Surface Mount. Switching control is made easier with the dcdc regulator's Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminal (s) are designed at QUAD . The 36 terminations can be used for a wide range of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. The nominal DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "LTC3774". Pins number 36 of switching converter in total. Switching converter is a type of Switching Regulator or Controllers in particular. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator. The dc to dc regulator is limited to 38V input voltage. The dc dc regulator's usual output current is 25A, which should be noted down when you start a project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 98 %. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. As a result, DC to DC voltage regulator has a value of OUTPUT VOLTAGE RANGE FROM 0.6 VOLT TO 3.5 VOLT so that the need can be met more directly. The dc to dc voltage regulator is from the PolyPhase? series.
