LM2745MTC/NOPB Overview
With its 14-TSSOP (0.173, 4.40mm Width) package, the switching controller fits the needs of most applications. Tube is the solid enclosure in which PMIC is packaged. A total of Transistor Driver dc switching's outputs can be handled by it. This dc control has a supply voltage and operating voltage of 3V~6V. Qualified to work in a -40°C~125°C TJ dc switcher. This switching controller can switch at 50kHz~1MHz. The Surface Mount allows it to be used for dc dc regulator in general. The dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking for efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Switching converters are designed with the terminal (s) at position DUAL . Various 14 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 3.3V. LM2745 can be used to locate other relevant dc to dc converter ics. 14 pins are present on switching converter. The test statistics indicate that DC regulator outputs a voltage of 13.5V. A starting point for a project is to note down the dc dc regulator's usual output current, which is 20A. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 86 %. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. DC regulators have a maximum frequency of 1MHz. When the dc switching is dormant, it uses 1.7mA. Input voltage can be set to 17V for nominal working status. This controller contains 1 phases.
