LTC3858EGN-1#PBF Overview
Capsuled in the 28-SSOP (0.154, 3.90mm Width) package, the switching controller suits most application needs. There is sufficient capacity to generate switching controller for outputs 2. PMIC is packaged in a solid enclosure of Tube. With this function, you can deal with Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 4V~38V. Worked in an dc switcher with a -40°C~125°C TJ rating. Switching can be done at 105kHz~835kHz 350kHz~535kHz with this switching controller. A generalization of dc dc regulator can be made using Surface Mount. For efficient switching control, the dcdc regulator features Enable, Frequency Control, Power Good, Soft Start. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. The switching converters's terminals (s) are designed at DUAL. A variety of terminations with 28 of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. 12V nominal DC switcher's voltage input. LTC3858 can be used to locate other relevant dc to dc converter ics. In total, switching converter has 28 pins. Switching converter type is specifically Switching Regulator or Controllers. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. The test statistics indicate that DC regulator outputs a voltage of 24V. A maximum voltage of 38V is accepted by the dc to dc regulator as an input voltage. This dc regulatorhas a max frequency of 850kHz. There are 1 channels for high-quality communication.
