LTC1149CS-5#TRPBF Product Details
LTC1149CS-5#TRPBF Overview
It comes in a 16-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. This dc motor controller can be used to generate outputs with 1 numbers. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with Up to 48V voltage are supplied and operated. A 0°C~70°C TA dc switcher is not a problem. A switching controller such as this can switch at a value of Up to 250kHz . It is suitable for general dc dc regulator when it is set to Surface Mount. DCDC regulator is controlled efficiently by Current Limit, Enable. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at DUAL . A variety of 16 terminations are available in dc switching. These dc dc converter ics adapt several control methods, including CONSTANT OFF TIME. DC switcher's input voltageis 12V volts. LTC1149 can be used to locate other relevant dc to dc converter ics. Switching converter is a special type of Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 5V. The dc to dc regulator is limited to 48V input voltage. The output value is set to the greatest value of 0.05A. There should be 3mA more than 3mA amps of current supplied to the controller.
