LTC3838IUHF-1#PBF Product Details

LTC3838IUHF-1#PBF Overview


With its 38-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. The dc motor controller is adquate to generate for 2 outputs. Packaged in solid enclosures, this pmic has a Tube rating. With Transistor Driver dc switching's output (s), it is able to handle it. dc control's supply and operating voltages are 4.5V~38V. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. Switching can be done at 200kHz~2MHz with this switching controller. 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. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at QUAD . 38 terminations with various dc switching's functions. DC switcher's voltage input is 15V. Other relevant dc to dc converter ics can be found by searching "LTC3838". There are 38 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator. If you start a project, note down the dc dc regulator's usual output current of 25A. This value is OUTPUT VOLTAGE RANGE FROM 0.6 VOLT TO 5.5 VOLT so that DC to DC voltage regulator better serves the purpose. Thare are switch converters of the PolyPhase? series.
