MAX1540AETJ+T Overview


The switching controller fits in the 32-WFQFN Exposed Pad package and is ideal for most applications. For 2 outputs, the dc motor controller is appropriate. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. The program can handle Transistor Driver dc switching's outputs (s). This dc control operates at 5.5V~28V and has a 5.5V~28V supply voltage. Suitable for a -40°C~85°C TA dc switcher. The switching controller can be switched at 170kHz~620kHz. dc dc regulator can be generalized using Surface Mount. The dcdc regulator features Current Limit, Enable, On Time Control, Power Good, Pulse Skipping, Saturation for efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. QUAD are the position of the terminal of the switching converters. A variety of 32 terminations are available in dc switching. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. In addition to "MAX1540", there are other relevant dc to dc converter ics you can find. Total pins of switching converter are 32. Switching converter type is specifically Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 5.5V voltage. You should note that the dc dc regulator's usual output current is 100mA. The duty cycle of the voltage regulator dc to dc can be set to 100 % on power-up or power-down to ensure reliability. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. There is a maximum frequency of 620kHz for this dc regulators. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 28V.
