LTC1149CN-5#PBF Overview
As a result of 16-DIP (0.300, 7.62mm) compact design, the switching controller is compatible with most applications. 1 outputs can be generated with the dc motor controller. An enclosure of Tube is used to package the PMIC. Transistor Driver dc switching's outputs (s) can be handled by it. This dc control has a supply voltage and operating voltage of Up to 48V. Worked in a 0°C~70°C TA dc switcher before. A switching controller such as this can switch at a value of Up to 250kHz . The Through Hole allows it to be used for dc dc regulator in general. To provide efficient switching control, Current Limit, Enable is included in the dcdc regulator. The switch converters are connected to a SWITCHING CONTROLLER analog IC. The switching converters's terminal (s) are designed at DUAL . There are many different types of terminations for 16. Some of the control techniques used by these dc dc converter ics are CONSTANT OFF TIME. A search for "LTC1149" will reveal other relevant dc to dc converter ics. 16 pins are present on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. The test statistics indicate that DC regulator outputs a voltage of 5V. The dc to dc regulator can only accept a maximum input voltage of 48V. DC regulators have a maximum frequency of 250kHz. Switching converter outputs current to the greatest value of 0.05A. It is important that the controller is supplied with 3mA more than 3mA volts of current.
