LTC3728LCGN#PBF Product Details
LTC3728LCGN#PBF Overview
As a result of 28-SSOP (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. There is sufficient capacity to generate switching controller for outputs 2. Packaged in solid enclosures, this pmic has a Tube rating. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching's4.5V~28V is the supply voltage and the operating voltage of the dc control. Workable in an dc switcher where 0°C~85°C TA is the 0°C~85°C TArm. Using this switching controller, it is possible to switch at 260kHz~550kHz. Surface Mount makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Enable, Power Good, Soft Start. An analog IC DUAL SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . The 28 terminations can be used for a wide range of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. LTC3728 can be used to locate other relevant dc to dc converter ics. Pins number 28 of switching converter in total. Switching converter type is specifically Switching Regulator or Controllers. Input voltage of dc dc voltage regulator must be 3.6V. Statistically, the DC regulator outputs 7V voltage. At most, the dc to dc regulator accepts 30V input voltage. You should note that the dc dc regulator's usual output current is 3A. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. DC regulator590kHz has the maximum frequency. Communication on 1 channels is high-quality.
