LTC1148HVCN-3.3#PBF Product Details
LTC1148HVCN-3.3#PBF Overview
This switching controller fits most application requirements since it is packaged in a 14-DIP (0.300, 7.62mm) package. 1 outputs can be generated with the dc motor controller. PMIC is packaged in a solid enclosure of Tube. Transistor Driver dc switching's outputs (s) are supported. 3.5V~20V is the operating voltage and supply voltage of the dc control. Suitable for a 0°C~70°C TA dc switcher. There is a switch at Up to 250kHz that can be used with this controller. dc dc regulator is made easier with Surface Mount. Current Limit, Enable is used for efficient switching control in the dcdc regulator. An analog IC SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . A variety of terminations with 14 of dc switching. It includes CONSTANT OFF TIME as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis set to 10V. You can find other relevant dc to dc converter ics by searching "LTC1148". In particular, switching converter belongs to the Switching Regulator or Controllers family. dc dc voltage regulators should have a minimum input voltage of 4V. DC regulator outputs 3.3V voltage according to the test statistics. A value of 0.05A is output as the maximum value of current. 2.3mA more than 2.3mA current should be supplied to the controller.
