14 Terminals 3V~6V 14-Pin LM2748 DC to DC converter IC SWITCHING CONTROLLER 50kHz~1MHz Transistor Driver
LM2748MTCX Overview
Capsuled in the 14-TSSOP (0.173, 4.40mm Width) package, the switching controller suits most application needs. The pmic is packaged in Tape & Reel (TR) solid enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThe supply and operating voltage of the dc control are 3V~6V. Qualified to work in a -40°C~125°C TJ dc switcher. This switching controller can switch at 50kHz~1MHz. Surface Mount makes it suitable for general dc dc regulator. The dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking for efficient switching control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the DUAL position. 14 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. 3.3V nominal DC switcher's voltage input. Other relevant dc to dc converter ics can be found by searching "LM2748". Switching converter has a total of 14 pins. The minimum input voltage of the dc dc voltage regulator should be 3V. According to the test statistics, DC regulator outputs 13.5V voltage. It should be fully noted that the dc to dc regulator only accepts 6V input voltage at most. The dc dc regulator's usual output current is 20A, which should be noted down when you start a project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 86 %. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sThe max frequency of the pmic can reach 1MHz. It is suggested that users apply 17V to the voltage regulator dc to dc in order to run it safely and reliably in a circuit. The dc switching utilizes 1.7mA when it is in a dormant state. This controller switches with 1 phases.
