LTC1148HVCN-5#PBF Overview


Capsuled in the 14-DIP (0.300, 7.62mm) package, the switching controller suits most application needs. It is sufficient to generate 1 outputs with this dc motor controller. PMIC packaging is solid with a Tube enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching's3.5V~20V is the supply voltage and the operating voltage of the dc control. A 0°C~70°C TA dc switcher is not a problem. This switching controller can switch at Up to 250kHz. Surface Mount makes it suitable for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable. The switch converters are connected to a SWITCHING CONTROLLER analog IC. A switching converters's terminal (s) sits at the DUAL position. A variety of dc switching's functions can be performed on 14 terminations. CONSTANT OFF TIME is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's input voltageis set to 10V. You can find other relevant dc to dc converter ics by searching "LTC1148". Specifically, switching converter falls under the Switching Regulator or Controllers category. The minimum input voltage of the dc dc voltage regulator should be 6V. The test statistics indicate that DC regulator outputs a voltage of 5V. The output value is set to the greatest value of 0.05A. A controller's current should not exceed 2.3mA.
