LTC1143LCS#PBF Overview

Capsuled in the 16-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. This dc motor controller can be used to generate outputs with 2 numbers. Packaging for the pmic consists of Tube solid enclosures. A total of Transistor Driver dc switching's outputs can be handled by it. This dc control has a supply voltage and operating voltage of 3.5V~16V. Suitable for work in a 0°C~70°C TA dc switcher. It can switch at Up to 400kHz. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. Switching converters are designed with the terminal (s) at position DUAL . The 16 terminations can be used for a wide range of dc switching. These dc dc converter ics adapt several control methods, including CONSTANT OFF TIME. DC switcher's input voltageis 10V volts. You can find other relevant dc to dc converter ics by searching "LTC1143". Specifically, switching converter falls under the Switching Regulator or Controllers category. 3.5V should be the minimum input voltage for the dc dc voltage regulator. DC regulator outputs 5.05V voltage according to the test statistics.
