LTC1149CS#TRPBF Overview
In the 16-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. For outputs of 1, this dc motor controller is suitable. There is a Tape & Reel (TR) solid enclosure around the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). dc controls with Up to 48V voltage are supplied and operated. Suitable for work in a 0°C~70°C TA dc switcher. This switching controller can switch at Up to 250kHz. The Surface Mount makes it ideal for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. The switching converters's terminal (s) are designed at DUAL . 16 terminations with various dc switching's functions. To name a few of the control techniques these dc dc converter ics adapt, it includes CONSTANT OFF TIME. The nominal DC switcher's voltage input is 12V. LTC1149 can be used to locate other relevant dc to dc converter ics. In particular, switching converter is a type of Switching Regulator or Controllers. Statistically, DC regulator outputs 1.25V volts. The dc to dc regulator is limited to 48V input voltage. Current is output to the greatest value of 0.05A. The controller should not be supplied with more current than 3mA.
