LTC1148HVCS-3.3#PBF Overview

In the 14-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. This dc motor controller can be used to generate outputs with 1 numbers. PMIC is packaged in a solid enclosure of Tube. It is capable of handling Transistor Driver dc switching's outputs (s). dc controls with 3.5V~20V voltage are supplied and operated. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. It can switch at Up to 250kHz. dc dc regulators can be carried out with Surface Mount. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Thare switching converters has a terminal (s) at DUAL . 14 terminations with various dc switching's functions. Some of the control techniques used by these dc dc converter ics are CONSTANT OFF TIME. DC switcher's voltage input of 10V. A search for "LTC1148" will reveal other relevant dc to dc converter ics. In total, switching converter has 14 pins. In particular, switching converter is a type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator must be 4V. DC regulator outputs 3.33V voltage according to the test statistics. A starting point for a project is to note down the dc dc regulator's usual output current, which is 50mA. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. The max frequency of the pmic can reach 250kHz. The controller should not be supplied with more current than 2.3mA.
