LTC1149CS-3.3#TRPBF Product Details
LTC1149CS-3.3#TRPBF Overview
Capsuled in the 16-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. 1 outputs are supported by the dc motor controller. Tape & Reel (TR) solid enclosure protects the pmic. There are Transistor Driver dc switching's output (s) that it can handle. Up to 48V is the operating voltage and supply voltage of the dc control. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. There is a switch at Up to 250kHz that can be used with this controller. The Surface Mount makes it ideal for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Terminal (s) of the switching converters are designed at the DUAL position. A variety of 16 terminations are available in dc switching. It includes CONSTANT OFF TIME as one of the control techniques dc dc converter ic adapts. The nominal DC switcher's voltage input is 12V. You can find other relevant dc to dc converter ics by searching "LTC1149". As determined by the test statistics, the output voltage of DC regulator is 3.3V. At most, the dc to dc regulator accepts 48V input voltage. There should be 3mA current exceeding 3mA supplied to the controller.
