LTC3785EUF Overview
With a 24-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. This dc motor controller can be used to generate outputs with 2 numbers. Packaged in solid enclosures, this pmic has a Tube rating. It is capable of handling Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 2.7V~10V. Suitable for work in a -40°C~85°C TA dc switcher. It can switch at 100kHz~1MHz. Surface Mount makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Soft Start. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. The switching converters's terminal (s) are designed at QUAD . Different dc switching's functions can be applied to 24 terminations. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis 3.6V volts. You can find other relevant dc to dc converter ics by searching "LTC3785". Specially, switching converter corresponds to type Switching Regulator or Controllers. Statistically, the DC regulator outputs 4.35V voltage. The output value is set to the greatest value of 3A.
