LTC3859AHFE#PBF Overview
Capsuled in the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller can be used for a wide range of applications. 3 outputs are supported by the dc motor controller. Packaging for the pmic consists of Tube solid enclosures. There are Transistor Driver dc switching's output (s) that it can handle. This dc control has a supply voltage and operating voltage of 4.5V~38V. Suitable for a -40°C~150°C TJ dc switcher. This switching controller can switch at 115kHz~835kHz 350kHz~535kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Power Good, Soft Start, Tracking. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. A variety of dc switching's functions can be performed on 38 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 12V. LTC3859 can be searched for other relevant dc to dc converter ics. Switching converter type is specifically Switching Regulator or Controllers. It is recommended that the input voltage of the dc dc voltage regulator be 4.5V. Statistically, DC regulator outputs 5.4V volts.
