LTC3859AHFE Product Details

LTC3859AHFE Overview


With its 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller fits the needs of most applications. The dc motor controller is adquate to generate for 3 outputs. Tube solid enclosure protects the pmic. The program can handle Transistor Driver dc switching's outputs (s). A 4.5V~38V voltage is supplied to the dc control and used for operating it. A -40°C~150°C TJ dc switcher is not a problem. With this switching controller, you can switch at 115kHz~835kHz 350kHz~535kHz. The Surface Mount makes it ideal for general dc dc regulator. Enable, Frequency Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the DUAL position. 38 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 12V. You can find other relevant dc to dc converter ics by searching "LTC3859". The type is a particular Switching Regulator or Controllers of switching converter. This dc dc voltage regulator should be powered by a voltage of 4.5V. According to the test statistics, DC regulator outputs 5.4V voltage.
