LTC1159CG#PBF Overview


It comes in the 20-SSOP (0.209, 5.30mm Width) package, which makes switching controller suitable for most applications. 1 outputs are supported by the dc motor controller. The pmic is packaged in Tube solid enclosure. With this function, you can deal with Transistor Driver dc switching's outputs (s). 4V~40V is the supply voltage and the operating voltage of the dc control. Suitable for a 0°C~70°C TA dc switcher. This switching controller 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. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of dc switching's functions can be performed on 20 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes CONSTANT OFF TIME. The DC switcher's nominal voltage is 12V. A search for "LTC1159" will reveal other relevant dc to dc converter ics. Switching converter has a total of 20 pins. In particular, switching converter belongs to the Switching Regulator or Controllers family. This dc dc voltage regulator should be powered by a voltage of 4V. A 1.25V voltage of DC regulator was detected in the test statistics. At most, the dc to dc regulator accepts 40V 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 regulator has a maximum frequency of 250kHz.
