LTC3859AEFE#TRPBF Product Details
LTC3859AEFE#TRPBF Overview
In the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller meets most application requirements. dc motor controller is suitable for 3 output generation. The pmic is packaged in Tape & Reel (TR) solid enclosure. With Transistor Driver dc switching's output (s), it is able to handle it. dc control's supply and operating voltages are 4.5V~38V. Qualified to work in a -40°C~125°C TJ dc switcher. This switching controller can switch at 115kHz~835kHz 350kHz~535kHz. dc dc regulator is made easier with 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. There are a DUAL terminal on the switching converters. An array of 38 terminations of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's input voltageis 12V volts. Other relevant dc to dc converter ics will be returned if you search "LTC3859". Switching converter is a special type of Switching Regulator or Controllers. The minimum input voltage of the dc dc voltage regulator should be 4.5V. Test statistics indicate DC regulator outputs 5.4V voltage.
