LTC1148HVCS-5#TRPBF Overview


Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. There is sufficient capacity to generate switching controller for outputs 1. PMIC packaging is solid with a Tape & Reel (TR) enclosure. Transistor Driver dc switching's outputs (s) can be handled by it. 3.5V~20V is the operating voltage and supply voltage of the dc control. Work well in dc switchers with a 0°C~70°C TA. The switching controller is capable of switching at the Up to 250kHz position. As it has a Surface Mount value, it can be used for general dc dc regulator. Current Limit, Enable is used for efficient switching control in the dcdc regulator. An analog IC SWITCHING CONTROLLER is connected to the switch converters. A switching converters's terminal (s) sits at the DUAL position. An array of 14 terminations of dc switching. These dc dc converter ics adapt several control methods, including CONSTANT OFF TIME. DC switcher's voltage input is 10V. You can find other relevant dc to dc converter ics by searching "LTC1148". In particular, switching converter belongs to the Switching Regulator or Controllers family. 3.5V should be the minimum input voltage for the dc dc voltage regulator. Statistically, DC regulator outputs 5V volts. It should be noted that the dc to dc regulator only accepts 20V voltage as input voltage. 0.05A is the greatest value switching converter outputs as current. In order to ensure proper operation, the controller should not receive more current than 2.3mA.
