LTC1148CS-5#TRPBF Overview
Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. 1 outputs can be generated with the dc motor controller. An enclosure of Tape & Reel (TR) is used to package the PMIC. With this function, you can deal with Transistor Driver dc switching's outputs (s). 3.5V~20V is the operating voltage and supply voltage of the dc control. Worked in an dc switcher with a 0°C~70°C TA rating. This switching controller can switch at Up to 250kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. There are a DUAL terminal on the switching converters. 14 terminations with a variety of function. CONSTANT OFF TIME is an example of one of the control techniques these dc dc converter ics adapt. It is inputted with a DC switcher's voltage of 10V. Other relevant dc to dc converter ics will be returned if you search "LTC1148". Switching converter type is specifically Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 3.5V. DC regulator outputs 5V voltage according to the test statistics. The dc to dc regulator can only accept 20V input voltage. As a result, switching converter outputs current to the greatest value possible (0.05A).
