LM2657MTCX/NOPB Overview

As a result of 28-TSSOP (0.173, 4.40mm Width) compact design, the switching controller is compatible with most applications. For outputs of 2, this dc motor controller is suitable. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. The program can handle Transistor Driver dc switching's outputs (s). 4.5V~28V is the supply voltage and the operating voltage of the dc control. Qualified to work in an dc switcher with -40°C~125°C TJ. In this switching controller, the switch can be set to 200kHz~500kHz. dc dc regulators can be carried out with Surface Mount. Current Limit, Enable, Frequency Control, Power Good, Soft Start is used for efficient switching control in the dcdc regulator. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. There are a DUAL terminal on the switching converters. Various 28 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 15V. LM2657 can be used to locate other relevant dc to dc converter ics. Switching converter has a total of 28 pins. There is a particular type of Switching Regulator or Controllers in switching converter. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator. The test statistics indicate that DC regulator outputs a voltage of 600mV. If you are starting a new project, you should note the dc dc regulator's typical output current is 20A. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 70 %. The Surface Mount makes DC switcher suitable for most applications and prototypes. DC regulator500kHz has the maximum frequency. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 28V. In dormant mode, 2.5mA is used.
