MAX1540ETJ+T Overview


Capsuled in the 32-WFQFN Exposed Pad package, the switching controller suits most application needs. There is sufficient capacity to generate switching controller for outputs 2. There is a Tape & Reel (TR) solid enclosure around the pmic. With Transistor Driver dc switching's output (s), it is able to handle it. This dc control has a supply voltage and operating voltage of 5.5V~28V. Work well in dc switchers with a -40°C~85°C TA. In this switching controller, the switch can be set to 170kHz~620kHz. dc dc regulator can be generalized using Surface Mount. Current Limit, Enable, On Time Control, Power Good, Pulse Skipping, Saturation provides dcdc regulator efficient switching control. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. switching converters terminal (s) are designed to be at QUAD. A variety of dc switching's functions can be performed on 32 terminations. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. A search for "MAX1540" will reveal other relevant dc to dc converter ics. Pins number 32 of switching converter in total. Switching converter type is specifically Switching Regulator or Controllers. A 5.5V voltage of DC regulator was detected in the test statistics. You should note down the dc dc regulator's usual output current of 5A when you start a project. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. DC regulator has a maximum frequency of 620kHz. In order for the voltage regulator dc to dc to perform safely and reliably in a circuit, users are advised to apply 28V.
