LTC3859ALIFE#TRPBF Product Details
LTC3859ALIFE#TRPBF Overview
This switching controller fits most application requirements since it is packaged in a 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package. This dc motor controller can be used to generate outputs with 3 numbers. The pmic is packaged in Tape & Reel (TR) solid enclosure. With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control operates at 4.5V~38V and has a 4.5V~38V supply voltage. Worked in an dc switcher with a -40°C~125°C TJ rating. A switching controller such as this can switch at a value of 115kHz~835kHz 350kHz~535kHz . dc dc regulator is made easier with Surface Mount. For efficient switching control, the dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. Thare switching converters has a terminal (s) at DUAL . A variety of terminations with 38 of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 12V. Other relevant dc to dc converter ics will be returned if you search "LTC3859". Switching converter is a type of Switching Regulator or Controllers in particular. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator.
