LTC3838IUHF-1#TRPBF Product Details
LTC3838IUHF-1#TRPBF Overview
This switching controller fits most application requirements since it is packaged in a 38-WFQFN Exposed Pad package. The dc motor controller is adquate to generate for 2 outputs. The pmic is packaged in Tape & Reel (TR) solid enclosure. Transistor Driver dc switching's outputs (s) are supported. 4.5V~38V is the supply voltage and the operating voltage of the dc control. Work well in dc switchers with a -40°C~125°C TJ. Using this switching controller, it is possible to switch at 200kHz~2MHz. dc dc regulator is made easier with Surface Mount. The dcdc regulator features Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking for efficient switching control. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. QUAD are the position of the terminal of the switching converters. Various 38 terminations. The DC switcher's nominal voltage is 15V. LTC3838 can be searched for other relevant dc to dc converter ics. Specifically, switching converter falls under the Switching Regulator or Controllers category. 4.5V should be the minimum input voltage for the dc dc voltage regulator. It should be fully noted that the dc to dc regulator only accepts 38V input voltage at most. To better satisfy the need, DC to DC voltage regulator has a value of OUTPUT VOLTAGE RANGE FROM 0.6 VOLT TO 5.5 VOLT. Thare are switch converters of the PolyPhase? series.
