TPS40091PWR Overview
It comes in the 24-TSSOP (0.173, 4.40mm Width) package, which makes switching controller suitable for most applications. There is enough capacity in the dc motor controller to generate the output for the 4 input. An enclosure of Tape & Reel (TR) is used to package the PMIC. PWM Signal dc switching's outputs (s) can be handled by it. 4.5V~15V is the operating voltage and supply voltage of the dc control. Worked in an dc switcher with a -40°C~85°C TA rating. The switching controller can be switched at 100kHz~1.2MHz. Surface Mount makes it suitable for general dc dc regulator. Switching control is made easier with the dcdc regulator's Current Limit, Enable, Frequency Control, Power Good, Soft Start. SWITCHING CONTROLLER analog IC connects the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. 24 terminations with a variety of function. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. 12V nominal DC switcher's voltage input. Searching "TPS40091" will return other relevant dc to dc converter ics. There are 24 pins on switching converter. The test statistics indicate that DC regulator outputs a voltage of 3.3V. normally, the dc dc regulator's output current is 120A, which you should keep in mind when starting a project. DC regulators have a maximum frequency of 1MHz. In order to satisfy the need, DC to DC voltage regulator has a value of IT CAN ALSO OPERATE WITH CURRENT MODE. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 15V. In dormant mode, 4mA is used. The maximum input voltage of this dc switcher is 15V, so users must limit the voltage accordingly. 4.5V is the required supply voltage. An output current greater than 120A cannot be provided by the dc switcher. Datasheets indicate that the switching converter can output 3.3V volts at its maximum. Its lowest voltage output is not less than 700mV.
