LM3478MM Overview


In the 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) package, the switching controller meets most application requirements. For 1 outputs, the dc motor controller is appropriate. Tape & Reel (TR) solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) are supported. This dc control has a supply voltage and operating voltage of 2.97V~40V. Suitable for a -40°C~125°C TJ dc switcher. In this switching controller, the switch can be set to 100kHz~1MHz. dc dc regulators can be carried out with Surface Mount. In order to control switching efficiently, the dcdc regulator features Enable, Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. The switching converters's terminals (s) are designed at DUAL. A variety of terminations with 8 of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. 12V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "LM3478". In total, switching converter has 8 pins. Specially, switching converter corresponds to type Switching Regulator or Controllers. Statistically, DC regulator outputs 1.26V volts. normally, the dc dc regulator's output current is 1A, which you should keep in mind when starting a project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. 400kHz is the frequency of the switching controller. During dormancy, the dc switching uses 2.7mA. It is possible to set the input voltage as 12V for nominal working statuses. Since the dc switcher's maximum input voltage is 45V, the voltage must be regulated accordingly. There will be 1A current output from the dc switcher above 1A.
