LTC1873EG#PBF Product Details
LTC1873EG#PBF Overview
The switching controller fits in the 28-SSOP (0.209, 5.30mm Width) package and is ideal for most applications. dc motor controller is suitable for 2 output generation. Packaged in solid enclosures, this pmic has a Tube rating. There are Transistor Driver dc switching's output (s) that it can handle. A 3V~7V voltage is supplied to the dc control and used for operating it. Suitable for work in a -40°C~85°C TA dc switcher. The Surface Mount makes it ideal for general dc dc regulator. Featured in the dcdc regulator is Enable, Soft Start which allows efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. There are a terminal (s) on the switching converters that are designed at DUAL. 28 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 5V. Other relevant dc to dc converter ics will be returned if you search "LTC1873". Total pins of switching converter are 28. A 3.5V voltage of DC regulator was detected in the test statistics. If you start a project, note down the dc dc regulator's usual output current of 25A. There is 550kHz frequency setting on the switching controller. The maximum input voltage of this dc switcher is 7V, so users must limit the voltage accordingly. A dc switcher can only produce an output current of 5A. A datasheet states that the switching converter can output 3.5V volts at its maximum. It is recommended that there be 1 channels for high-quality communication.
