MAX1956ETI+T Overview


This switching controller fits most application requirements since it is packaged in a 28-WFQFN Exposed Pad package. For outputs of 2, this dc motor controller is suitable. A solid enclosure of Tape & Reel (TR) surrounds pmic. It is capable of handling Transistor Driver dc switching's outputs (s). A 1.6V~5.5V voltage is supplied to the dc control and used for operating it. Suitable for working in an dc switcher that has a -40°C~85°C TA. Switching can be done at 600kHz with this switching controller. dc dc regulators can be carried out with Surface Mount. DCDC regulator is controlled efficiently by Current Limit, Enable, Sequencing. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at QUAD . 28 terminations with various dc switching's functions. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input of 3.3V. You can find other relevant dc to dc converter ics by searching "MAX1956". There are 28 pins on switching converter. This dc dc voltage regulator should be powered by a voltage of 1.6V. Statistically, the DC regulator outputs 4.95V voltage. It's important to remember that the dc dc regulator's normaloutput current is 25A, so you should note it down when starting a new project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 93 %. DC switcher's Surface Mount qualifies it for most applications and prototypes. 660kHz is the maximum frequency of this dc regulators. Users should apply 5.5V to operate the voltage regulator dc to dc safely and reliably. 100μA volts is the supply current. There is a nominal current supply of 25A for this the controllers dc.
