LTC3857EGN-1#TRPBF Overview


It comes in the 28-SSOP (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. The dc motor controller is adquate to generate for 2 outputs. An enclosure of Tape & Reel (TR) is used to package the PMIC. With this function, you can deal with Transistor Driver dc switching's outputs (s). 4V~38V is the operating voltage and supply voltage of the dc control. Suitable for work in a -40°C~125°C TJ dc switcher. The switching controller is capable of switching at the 105kHz~835kHz 350kHz~535kHz position. A generalization of dc dc regulator can be made using Surface Mount. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. The switching converters's terminals (s) are designed at DUAL. 28 terminations with various dc switching's functions. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. In addition to "LTC3857", there are other relevant dc to dc converter ics you can find. There are 28 pins on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. It is recommended that the input voltage of the dc dc voltage regulator be 4V. A 24V voltage of DC regulator was detected in the test statistics. A maximum voltage of 38V is accepted by the dc to dc regulator as an input voltage. DC regulators have a maximum frequency of 850kHz. Basically, it's a dc to dc voltage regulator from the PolyPhase? series. Channels 1 are required for high-quality communication.
