32 Terminals 4V~38V 32-Pin LTC3857 DC to DC converter IC DUAL SWITCHING CONTROLLER 2 Outputs 105kHz~835kHz 350kHz~535kHz Transistor Driver
LTC3857EUH#TRPBF Overview
The switching controller fits in the 32-WFQFN Exposed Pad package and is ideal for most applications. dc motor controller is suitable for 2 output generation. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. There are Transistor Driver dc switching's output (s) that it can handle. A 4V~38V voltage is supplied to the dc control and used for operating it. Suitable for work in a -40°C~125°C TJ dc switcher. With this switching controller, you can switch at 105kHz~835kHz 350kHz~535kHz. The Surface Mount makes it ideal for general dc dc regulator. Featured in the dcdc regulator is Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking which allows efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. There are a terminal (s) on the switching converters that are designed at QUAD. 32 terminations with various dc switching's functions. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The DC switcher's nominal voltage is 12V. Other relevant dc to dc converter ics will be returned if you search "LTC3857". Total pins of switching converter are 32. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. A 24V voltage of DC regulator was detected in the test statistics. Considering the dc to dc regulator can only accept 38V input voltage, it is important to take note of this. There is a maximum frequency of 850kHz for this dc regulators. It belongs to the dc to dc voltage regulator series PolyPhase®. It is recommended that there be 1 channels for high-quality communication.
