LTC1148LCS#PBF Overview

The switching controller fits in the 14-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. The dc motor controller is adquate to generate for 1 outputs. PMIC is packaged in a solid enclosure of Tube. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with 3.5V~20V voltage are supplied and operated. A 0°C~70°C TA dc switcher is not a problem. It can switch at Up to 250kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Current Limit, Enable provides dcdc regulator efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. The switching converters's terminal (s) are designed at DUAL . There are many different types of terminations for 14. These dc dc converter ics adapt a variety of control techniques, including CONSTANT OFF TIME. The nominal DC switcher's voltage input is 10V. You can find other relevant dc to dc converter ics by searching "LTC1148". Switching converter has a total of 14 pins. Specifically, switching converter falls under the Switching Regulator or Controllers category. It is recommended to use 3.5V as the minimum input voltage of dc dc voltage regulator. The dc to dc regulator can only accept 20V input voltage. 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. DC switcher's Surface Mount qualifies it for most applications and prototypes. 250kHz is the maximum frequency of this dc regulators.
