LTC3859AMPUHF#PBF Overview

The switching controller fits in the 38-WFQFN Exposed Pad package and is ideal for most applications. For outputs of 3, this dc motor controller is suitable. PMIC packaging is solid with a Tube enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 4.5V~38V are the dc control's supply voltage and operating voltage, respectively. Suitable for working in an dc switcher that has a -55°C~150°C TJ. The switching controller can be switched at 115kHz~835kHz 350kHz~535kHz. The Surface Mount allows it to be used for dc dc regulator in general. The dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking for efficient switching control. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. QUAD are the position of the terminal of the switching converters. The 38 terminations can be used for a wide range of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input is 12V. Other relevant dc to dc converter ics can be found by searching "LTC3859". Specially, switching converter corresponds to type Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 4.5V. The test statistics indicate that DC regulator outputs a voltage of 5.4V.
