LTC1148CS#PBF Overview
Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. 1 outputs are supported by the dc motor controller. An enclosure of Tube is used to package the PMIC. A total of Transistor Driver dc switching's outputs can be handled by it. This dc control operates at 3.5V~20V and has a 3.5V~20V supply voltage. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. The switching controller can be switched at Up to 250kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. The dcdc regulator features Current Limit, Enable for efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. A switching converters's terminal (s) sits at the DUAL position. Various 14 terminations. A few of the control techniques these dc dc converter ics adapt include CONSTANT OFF TIME. A DC switcher's nominal voltage of 10V is input. LTC1148 can be searched for other relevant dc to dc converter ics. Switching converter has a total of 14 pins. In particular, switching converter is a type of Switching Regulator or Controllers. As determined by the test statistics, the output voltage of DC regulator is 5V. If you are starting a new project, you should note the dc dc regulator's typical output current is 50mA. This Surface Mount makes DC switcher suitable for most prototypes and applications. A frequency of 250kHz is set for the switching controller. The maximum input voltage of this dc switcher is 20V, so users must limit the voltage accordingly. Voltage 3.5V must be supplied. 1.6mA current flow input could satisfy the switching converter for operation.
