LTC1439CGW#PBF Overview


This switching controller fits most application requirements since it is packaged in a 36-BSOP (0.295, 7.50mm Width) package. It is sufficient to generate 2 outputs with this dc motor controller. Packaged in solid enclosures, this pmic has a Tube rating. A total of Transistor Driver dc switching's outputs can be handled by it. A 3.5V~30V voltage is supplied to the dc control and used for operating it. Worked in a 0°C~70°C TA dc switcher before. Switching can be done at Up to 400kHz with this switching controller. dc dc regulator is made easier with Surface Mount. In order to control switching efficiently, the dcdc regulator features Enable, Power on Reset, Soft Start. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of dc switching's functions can be performed on 36 terminations. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. Other relevant dc to dc converter ics can be found by searching "LTC1439". 36 pins are present on switching converter. Switching converter is a special type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 3.5V. As determined by the test statistics, the output voltage of DC regulator is 5V. DC regulator138kHz has the maximum frequency. 2A is the largest value switching converter outputs.
