LM2657MTCX Overview
As a result of 28-TSSOP (0.173, 4.40mm Width) compact design, the switching controller is compatible with most applications. 2 outputs are supported by the dc motor controller. A solid enclosure of Tape & Reel (TR) surrounds pmic. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with 4.5V~28V voltage are supplied and operated. Suitable for a -40°C~125°C TJ dc switcher. This switching controller can switch at 200kHz~500kHz. The Surface Mount value 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. An analog IC DUAL SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. There are many different types of terminations for 28. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. LM2657 can be searched for other relevant dc to dc converter ics. There are a total of 28 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. 4.5V should be the minimum input voltage for the dc dc voltage regulator. According to the test statistics, DC regulator outputs 600mV voltage. normally, the dc dc regulator's output current is 20A, which you should keep in mind when starting a project. The duty cycle of the voltage regulator dc to dc can be set to 70 % 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. This dc regulatorhas a max frequency of 500kHz. Users should apply 28V to operate the voltage regulator dc to dc safely and reliably. During dormancy, the dc switching uses 2.5mA.
