LTC3731HG#PBF Overview

The switching controller fits in the 36-SSOP (0.209, 5.30mm Width) package and is ideal for most applications. 3 outputs are supported by the dc motor controller. The pmic is packaged in Tube solid enclosure. With this function, you can deal with Transistor Driver dc switching's outputs (s). dc controls with 3.8V~7V voltage are supplied and operated. Worked in an dc switcher with a -40°C~140°C TJ rating. The switching controller can be switched at 225kHz~680kHz. dc dc regulator is made easier with Surface Mount. To ensure efficient switching, this dcdc regulator features a Enable, Phase Control, Power Good, Soft Start. SWITCHING CONTROLLER analog IC connects the switch converters. DUAL are the position of the terminal of the switching converters. Various 36 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's input voltageis 5V volts. In addition to "LTC3731", there are other relevant dc to dc converter ics you can find. Total pins of switching converter are 36. Particularly, switching converter is a type of Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 32V voltage. You should note down the dc dc regulator's usual output current of 5A when you start a project. A frequency of 600kHz is set for the switching controller. PolyPhase? series dc to dc voltage regulator belong to this series. In order to limit the voltage of a dc switcher whose maximum input voltage is 7V, it must be limited by the user. A dc switcher can only produce an output current of 5A. Its datasheet indicates the switching converter can output a maximum of 32V volts. Channels 1 are required for high-quality communication.
