MAX1540AETJ+ Overview
This switching controller fits most application requirements since it is packaged in a 32-WFQFN Exposed Pad package. For 2 outputs, the dc motor controller is appropriate. PMIC packaging is solid with a Tube enclosure. With Transistor Driver dc switching's output (s), it is able to handle it. 5.5V~28V is the operating voltage and supply voltage of the dc control. Suitable for working in an dc switcher that has a -40°C~85°C TA. Using this switching controller, it is possible to switch at 170kHz~620kHz. A generalization of dc dc regulator can be made using Surface Mount. Current Limit, Enable, On Time Control, Power Good, Pulse Skipping, Saturation provides dcdc regulator efficient switching control. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. There are a terminal (s) on the switching converters that are designed at QUAD. There are many different types of terminations for 32. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. Searching "MAX1540" will return other relevant dc to dc converter ics. 32 pins are present on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. Test statistics indicate DC regulator outputs 5.5V voltage. If you are starting a new project, you should note the dc dc regulator's typical output current is 5A. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 100 %. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. This dc regulatorhas a max 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. There is 1μA supply current for it.
