LTC1142HVCG#TRPBF Overview


Capsuled in the 28-SSOP (0.209, 5.30mm Width) package, the switching controller can be used for a wide range of applications. 2 outputs are supported by the dc motor controller. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. With Transistor Driver dc switching's output (s), it is able to handle it. A 3.5V~18V voltage is supplied to the dc control and used for operating it. Qualified to work in a 0°C~70°C TA dc switcher. The switching controller is capable of switching at the Up to 250kHz position. dc dc regulator is made easier with Surface Mount. Featured in the dcdc regulator is Current Limit, Enable which allows efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at DUAL . The 28 terminations can be used for a wide range of dc switching. Some of the control techniques adapted by these dc dc converter ics include CONSTANT OFF TIME. DC switcher's voltage input is 10V. LTC1142 can be searched for other relevant dc to dc converter ics. dc dc voltage regulators should have a minimum input voltage of 3.5V. As a result, switching converter outputs current to the greatest value possible (0.05A).
