LTC3731CUH#PBF Overview
Capsuled in the 32-WFQFN Exposed Pad package, the switching controller suits most application needs. There is sufficient capacity to generate switching controller for outputs 3. PMIC is packaged in a solid enclosure of Tube. There are Transistor Driver dc switching's output (s) that it can handle. 3.8V~7V is the supply voltage and the operating voltage of the dc control. Suitable for a 0°C~70°C TA dc switcher. With this switching controller, you can switch at 225kHz~680kHz. The Surface Mount value makes it suitable for general dc dc regulator. Featured in the dcdc regulator is Enable, Phase Control, Power Good, Soft Start which allows efficient switching control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminals (s) are designed at QUAD. Different dc switching's functions can be applied to 32 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 5V. LTC3731 can be searched for other relevant dc to dc converter ics. In total, switching converter has 32 pins. Switching converter is a special type of Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 4.5V. DC regulator outputs 600mV voltage according to the test statistics. You should note that the dc dc regulator's usual output current is 240A. DC regulator's maximum frequency is 750kHz. The dc to dc voltage regulator belongs to the PolyPhase? series. A high-quality communication requires 1 channels.
