LTC1148LCS-3.3#PBF Overview
As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. There is sufficient capacity to generate switching controller for outputs 1. PMIC is packaged in a solid enclosure of Tube. A total of Transistor Driver dc switching's outputs can be handled by it. 3.5V~20V is the operating voltage and supply voltage of the dc control. Suitable for work in a 0°C~70°C TA dc switcher. There is a switch at Up to 250kHz that can be used with this controller. The Surface Mount makes it ideal for general dc dc regulator. The dcdc regulator features Current Limit, Enable for efficient switching control. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . 14 terminations with various dc switching's functions. These dc dc converter ics adapt a variety of control techniques, including CONSTANT OFF TIME. It is inputted with a DC switcher's voltage of 10V. A search for "LTC1148" will reveal other relevant dc to dc converter ics. There are 14 pins on switching converter. In particular, switching converter belongs to the Switching Regulator or Controllers family. Input voltage of dc dc voltage regulator should be 3.5V. As determined by the test statistics, the output voltage of DC regulator is 3.33V. Voltages 20V are the maximum that the dc to dc regulator will accept. In most cases, the dc dc regulator's output current is 50mA. This information should be noted when you begin working with the component. This Surface Mount makes DC switcher suitable for most prototypes and applications. 250kHz is the maximum frequency of this dc regulators.
