LTC3838EUHF-1#TRPBF Overview
Capsuled in the 38-WFQFN Exposed Pad package, the switching controller suits most application needs. dc motor controller is suitable for 2 output generation. A solid enclosure of Tape & Reel (TR) surrounds pmic. There are Transistor Driver dc switching's output (s) that it can handle. 4.5V~38V is the supply voltage and the operating voltage of the dc control. Suitable for work in a -40°C~125°C TJ dc switcher. This switching controller can switch at 200kHz~2MHz. The Surface Mount value makes it suitable for general dc dc regulator. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. There are a terminal (s) on the switching converters that are designed at QUAD. A variety of dc switching's functions can be performed on 38 terminations. There is a DC switcher's nominal voltage of 15V. You can find other relevant dc to dc converter ics by searching "LTC3838". In particular, switching converter is a type of Switching Regulator or Controllers. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator. The dc to dc regulator can only accept a maximum input voltage of 38V. Hence, OUTPUT VOLTAGE RANGE FROM 0.6 VOLT TO 5.5 VOLT is used to better suit the DC to DC voltage regulator's situation. It belongs to the PolyPhase? series of dc to dc voltage regulator.
