LTC3858IGN-1#PBF Overview


Capsuled in the 28-SSOP (0.154, 3.90mm Width) package, the switching controller suits most application needs. 2 outputs can be generated with the dc motor controller. PMIC is packaged in a solid enclosure of Tube. There are Transistor Driver dc switching's output (s) that it can handle. A 4V~38V voltage is supplied to the dc control and used for operating it. Qualified to work in a -40°C~125°C TJ dc switcher. A switching controller such as this can switch at a value of 105kHz~835kHz 350kHz~535kHz . The Surface Mount allows it to be used for dc dc regulator in general. Enable, Frequency Control, Power Good, Soft Start provides dcdc regulator efficient switching control. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. switching converters terminal (s) are designed to be at DUAL. Various 28 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 12V. Searching "LTC3858" will return other relevant dc to dc converter ics. 28 pins are on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. dc dc voltage regulators should have a minimum input voltage of 4V. A 24V voltage of DC regulator was detected in the test statistics. At most, the dc to dc regulator accepts 38V input voltage. This dc regulatorhas a max frequency of 850kHz. Channels 1 are required for high-quality communication.
