LTC3838EUHF-1#PBF Overview
Capsuled in the 38-WFQFN Exposed Pad package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 2 outputs. An enclosure of Tube is used to package the PMIC. Transistor Driver dc switching's outputs (s) can be handled by it. The supply and operating voltage of the dc control are 4.5V~38V. Suitable for work in a -40°C~125°C TJ dc switcher. Switching can be done at 200kHz~2MHz with this switching controller. The Surface Mount value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at QUAD . Different dc switching's functions can be applied to 38 terminations. The nominal DC switcher's voltage input is 15V. In addition to "LTC3838", there are other relevant dc to dc converter ics you can find. Switching converter type is specifically Switching Regulator or Controllers. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V. It should be fully noted that the dc to dc regulator only accepts 38V input voltage at most. As a result, DC to DC voltage regulator has a value of OUTPUT VOLTAGE RANGE FROM 0.6 VOLT TO 5.5 VOLT so that the need can be met more directly. A dc to dc voltage regulator in the PolyPhase? series, it belongs to this family.
