LTC1148HVCS-5#PBF Overview


As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. This dc motor controller can be used to generate outputs with 1 numbers. Packaging for the pmic consists of Tube solid enclosures. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 3.5V~20V are the dc control's supply voltage and operating voltage, respectively. Worked in a 0°C~70°C TA dc switcher before. The switching controller is capable of switching at the Up to 250kHz position. As it has a Surface Mount value, it can be used for general dc dc regulator. For efficient switching control, the dcdc regulator features Current Limit, Enable. SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . Various 14 terminations. It includes CONSTANT OFF TIME as one of the control techniques dc dc converter ic adapts. 10V nominal DC switcher's voltage input. In addition to "LTC1148", there are other relevant dc to dc converter ics you can find. There are a total of 14 pins on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. dc dc voltage regulators should have a minimum input voltage of 6V. DC regulator outputs 5V voltage based on test statistics. The max frequency of the pmic can reach 250kHz. A value of 0.05A is output as the maximum value of current. In order to ensure proper operation, the controller should not receive more current than 2.3mA.
