LTC3859AHFE#TRPBF Overview
With a 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller is suitable for a wide range of applications. 3 outputs are supported by the dc motor controller. PMIC packaging is solid with a Tape & Reel (TR) enclosure. Transistor Driver dc switching's outputs (s) are supported. DC control operates at 4.5V~38V volts and has 4.5V~38V supply voltage. Qualified to work in an dc switcher with -40°C~150°C TJ. A switching controller such as this can switch at a value of 115kHz~835kHz 350kHz~535kHz . The Surface Mount allows it to be used for dc dc regulator in general. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Power Good, Soft Start, Tracking. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. A variety of dc switching's functions can be performed on 38 terminations. 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 12V. Other relevant dc to dc converter ics can be found by searching "LTC3859". Switching converter type is specifically Switching Regulator or Controllers. It is recommended that the dc dc voltage regulator's minimum input voltage be 4.5V. DC regulator outputs 5.4V voltage according to the test statistics.
