LTC3838EFE#PBF Overview
It comes in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, which makes switching controller suitable for most applications. It is sufficient to generate 2 outputs with this dc motor controller. Packaging for the pmic consists of Tube solid enclosures. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4.5V~38V. Work well in dc switchers with a -40°C~125°C TJ. Using this switching controller, it is possible to switch at 200kHz~2MHz. The Surface Mount value makes it suitable for general dc dc regulator. To provide efficient switching control, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. A switching converters's terminal (s) sits at the DUAL position. The 38 terminations can be used for a wide range of dc switching. 15V nominal DC switcher's voltage input. A search for "LTC3838" will reveal other relevant dc to dc converter ics. Specifically, switching converter falls under the Switching Regulator or Controllers category. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V. Statistically, DC regulator outputs 5.3V volts. Voltages 38V are the maximum that the dc to dc regulator will accept. This value is OPERATE IN ADJUSTABLE MODE FROM 0.6 TO 5.5V so that DC to DC voltage regulator better serves the purpose. The dc to dc voltage regulator is from the PolyPhase? series.
