LTC3859AMPFE Product Details
LTC3859AMPFE Overview
In the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller meets most application requirements. There is enough capacity in the dc motor controller to generate the output for the 3 input. PMIC packaging is solid with a Tube enclosure. There are Transistor Driver dc switching's output (s) that it can handle. Voltages 4.5V~38V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in an dc switcher with -55°C~150°C TJ. The switching controller can be switched at 115kHz~835kHz 350kHz~535kHz. Surface Mount makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. Thare switching converters has a terminal (s) at DUAL . 38 terminations with a variety of function. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. Other relevant dc to dc converter ics can be found by searching "LTC3859". Specifically, switching converter falls under the Switching Regulator or Controllers category. The minimum input voltage of the dc dc voltage regulator should be 4.5V. As determined by the test statistics, the output voltage of DC regulator is 5.4V.
