LTC3728LZEUH#PBF Product Details
LTC3728LZEUH#PBF Overview
Capsuled in the 32-WFQFN Exposed Pad package, the switching controller suits most application needs. There is enough capacity in the dc motor controller to generate the output for the 2 input. Packaged in solid enclosures, this pmic has a Tube rating. With Transistor Driver dc switching's output (s), it is able to handle it. 4.5V~28V is the operating voltage and supply voltage of the dc control. Suitable for working in an dc switcher that has a -40°C~85°C TA. Switching can be done at 260kHz~550kHz with this switching controller. The Surface Mount makes it ideal for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Enable, Power Good, Soft Start. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. Switching converters are designed with the terminal (s) at position QUAD . Various 28 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 15V. LTC3728 can be searched for other relevant dc to dc converter ics. Pins number 32 of switching converter in total. dc dc voltage regulators should have a minimum input voltage of 4.5V. The test statistics indicate that DC regulator outputs a voltage of 7V. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. There is a maximum frequency of 590kHz on this dc regulators. 3A is the greatest value switching converter outputs as current. The number of channels available for high-quality communication is 1.
