Description
LTC1149CS-5#PBF Overview
It comes in the 16-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. Packaging for the pmic consists of Tube solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are Up to 48V. Qualified to work in an dc switcher with 0°C~70°C TA. The switching controller can be switched at Up to 250kHz. dc dc regulators can be carried out with Surface Mount. Current Limit, Enable provides dcdc regulator efficient switching control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a DUAL terminal on the switching converters. Different dc switching's functions can be applied to 16 terminations. Some of the control techniques adapted by these dc dc converter ics include CONSTANT OFF TIME. DC switcher's voltage input of 12V. LTC1149 can be searched for other relevant dc to dc converter ics. In total, switching converter has 16 pins. Switching converter type is specifically Switching Regulator or Controllers. Statistically, DC regulator outputs 5.05V volts. This dc to dc regulator accepts only 48V input voltage at most. In most cases, the output current of the dc dc regulator will be 50mA, so note that when you start the project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 100 %. DC switcher's Surface Mount qualifies it for most applications and prototypes. 250kHz is the maximum frequency of this dc regulators. A controller's current should not exceed 3mA. This controller contains 1 phases.
