LTC1149CS-5#TRPBF Overview


As a result of 16-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. This dc motor controller can be used to generate outputs with 1 numbers. Tape & Reel (TR) solid enclosure protects the pmic. With Transistor Driver dc switching's output (s), it is able to handle it. A Up to 48V voltage is supplied to the dc control and used for operating it. A 0°C~70°C TA dc switcher is not a problem. There is a switch at Up to 250kHz that can be used with this controller. As it has a Surface Mount value, it can be used for general dc dc regulator. To provide efficient switching control, Current Limit, Enable is included in the dcdc regulator. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. A switching converters's terminal (s) sits at the DUAL position. A variety of dc switching's functions can be performed on 16 terminations. CONSTANT OFF TIME is an example of one of the control techniques these dc dc converter ics adapt. The nominal DC switcher's voltage input is 12V. You can find other relevant dc to dc converter ics by searching "LTC1149". Specially, switching converter corresponds to type Switching Regulator or Controllers. DC regulator outputs 5V voltage based on test statistics. It should be fully noted that the dc to dc regulator only accepts 48V input voltage at most. 0.05A is the largest value switching converter outputs. It is important that the controller is supplied with 3mA more than 3mA volts of current.
