LTC3728LEGN-1 Product Details

LTC3728LEGN-1 Overview


It comes in the 28-SSOP (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. It is sufficient to generate 2 outputs with this dc motor controller. Packaging for the pmic consists of Tube solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 4.5V~28V. Qualified to work in an dc switcher with -40°C~85°C TA. The switching controller can be switched at 260kHz~550kHz. dc dc regulators can be carried out with Surface Mount. Enable, Power Good, Soft Start provides dcdc regulator efficient switching control. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. There are a DUAL terminal on the switching converters. Different dc switching's functions can be applied to 28 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. LTC3728 can be searched for other relevant dc to dc converter ics. Switching converter type is specifically Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 4.5V. Statistically, DC regulator outputs 3.35V volts. 3A is the greatest value switching converter outputs as current.
