LTC1149CS#PBF Overview


Capsuled in the 16-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 1 outputs. Tube is the solid enclosure in which PMIC is packaged. With this function, you can deal with Transistor Driver dc switching's outputs (s). Up to 48V is the supply voltage and the operating voltage of the dc control. Suitable for work in a 0°C~70°C TA dc switcher. There is a switch at Up to 250kHz that can be used with this controller. The Surface Mount value makes it suitable for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable. SWITCHING CONTROLLER analog IC connects the switch converters. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of terminations with 16 of dc switching. Some of the control techniques used by these dc dc converter ics are CONSTANT OFF TIME. Other relevant dc to dc converter ics can be found by searching "LTC1149". In total, switching converter has 16 pins. Particularly, switching converter is a type of Switching Regulator or Controllers. A 3.3V voltage of DC regulator was detected in the test statistics. If you start a project, note down the dc dc regulator's usual output current of 50mA. DC switcher's Surface Mount qualifies it for most applications and prototypes. There is a maximum frequency of 250kHz on this dc regulators. The maximum input voltage of this dc switcher is 60V, so users must limit the voltage accordingly. There must be a -15V supply voltage. There will be 50mA output current greater than 50mA from the dc switcher. You should not supply more current than 3mA to the controller. Datasheets indicate that the switching converter can output 5.2V volts at its maximum. At its lowest voltage, the voltage controller does not produce less than 4.9V.
