LTC1148CN-5#PBF Overview
In the 14-DIP (0.300, 7.62mm) package, the switching controller meets most application requirements. 1 outputs can be generated with the dc motor controller. A solid enclosure of Tube surrounds pmic. Transistor Driver dc switching's outputs (s) are supported. dc controls with 3.5V~20V voltage are supplied and operated. A 0°C~70°C TA dc switcher is not a problem. With this switching controller, you can switch at Up to 250kHz. The Surface Mount makes it ideal for general dc dc regulator. To provide efficient switching control, Current Limit, Enable is included in the dcdc regulator. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. The switching converters's terminal (s) are designed at DUAL . 14 terminations with various dc switching's functions. These dc dc converter ics adapt several control methods, including CONSTANT OFF TIME. The DC switcher's nominal voltage is 10V. LTC1148 can be used to locate other relevant dc to dc converter ics. Total pins of switching converter are 14. Particularly, switching converter is a type of Switching Regulator or Controllers. A 5.05V voltage of DC regulator was detected in the test statistics. It's important to remember that the dc dc regulator's normaloutput current is 50mA, so you should note it down when starting a new project. This Through Hole makes DC switcher suitable for most prototypes and applications. It is estimated that this dc regulatorhas a maximum frequency of 250kHz. In order to use a 3.5V voltage supply, switching controller is necessary to have one.
