LTC1147CS8-5#PBF Overview
As a result of 8-SOIC (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. 1 outputs can be generated with the dc motor controller. There is a Tube solid enclosure around the pmic. With Transistor Driver dc switching's output (s), it is able to handle it. Voltages 3.5V~14V are the dc control's supply voltage and operating voltage, respectively. Suitable for work in a 0°C~70°C TA dc switcher. Surface Mount makes it suitable for general dc dc regulator. Current Limit, Enable provides dcdc regulator efficient switching control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminals (s) are designed at DUAL. A variety of dc switching's functions can be performed on 8 terminations. CONSTANT OFF TIME is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's input voltageis set to 10V. Search for "LTC1147" to find other relevant dc to dc converter ics. Switching converter type is specifically Switching Regulator or Controllers. Input voltage of dc dc voltage regulator must be 4V. A 5V voltage of DC regulator was detected in the test statistics. This controller can operate at a frequency up to 400kHz.
