LM3478MAX/NOPB Overview
In the 8-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. For 1 outputs, the dc motor controller is appropriate. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. Transistor Driver dc switching's outputs (s) are supported. dc controls with 2.97V~40V voltage are supplied and operated. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. There is a switch at 100kHz~1MHz that can be used with this controller. As it has a Surface Mount value, it can be used for general dc dc regulator. For efficient switching control, the dcdc regulator features Enable, Frequency Control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . A variety of terminations with 8 of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input is 12V. In addition to "LM3478", there are other relevant dc to dc converter ics you can find. Switching converter has a total of 8 pins. Switching converter type is specifically Switching Regulator or Controllers. It is recommended that the input voltage of the dc dc voltage regulator be 2.97V. 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. The duty cycle of the voltage regulator dc to dc can be set to 100 % on power-up or power-down to ensure reliability. This Surface Mount makes DC switcher suitable for most prototypes and applications. The max frequency of the pmic can reach 1MHz. For safe and reliable operation in a circuit, voltage regulator dc to dc is suggested that users apply 40V. The dc switching utilizes 2.7mA when it is in a dormant state.
