LTC1142HVCG#TRPBF Product Details
LTC1142HVCG#TRPBF Overview
In the 28-SSOP (0.209, 5.30mm Width) package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 2. There is a Tape & Reel (TR) solid enclosure around the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 3.5V~18V volts and has 3.5V~18V supply voltage. Suitable for working in an dc switcher that has a 0°C~70°C TA. It can switch at Up to 250kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. To provide efficient switching control, Current Limit, Enable is included in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. DUAL are the position of the terminal of the switching converters. Various 28 terminations. This dc dc converter ic uses a variety of control techniques, including CONSTANT OFF TIME. There is a DC switcher's nominal voltage of 10V. In addition to "LTC1142", there are other relevant dc to dc converter ics you can find. It is recommended that the dc dc voltage regulator's minimum input voltage be 3.5V. As a result, switching converter outputs current to the greatest value possible (0.05A).
