LTC1148HVCS-3.3#TRPBF Overview
As a result of 14-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. Transistor Driver dc switching's outputs (s) are supported. The supply and operating voltage of the dc control are 3.5V~20V. Work well in dc switchers with a 0°C~70°C TA. With this switching controller, you can switch at Up to 250kHz. dc dc regulator is made easier with Surface Mount. Switching control is made easier with the dcdc regulator's Current Limit, Enable. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. Various 14 terminations. Some of the control techniques used by these dc dc converter ics are CONSTANT OFF TIME. The nominal DC switcher's voltage input is 10V. A search for "LTC1148" will reveal other relevant dc to dc converter ics. Switching converter is a special type of Switching Regulator or Controllers. It is recommended to use 3.5V as the minimum input voltage of dc dc voltage regulator. DC regulator outputs 3.3V voltage based on test statistics. The dc to dc regulator is limited to 20V input voltage. Whenever the current value is 0.05A, switching converter outputs the highest possible value. It is important that the controller is supplied with 2.3mA more than 2.3mA volts of current.
