LTC3784HUFD#PBF Overview

Capsuled in the 28-WFQFN Exposed Pad package, the switching controller suits most application needs. 2 outputs can be generated with the dc motor controller. An enclosure of Tube is used to package the PMIC. It is capable of handling Transistor Driver dc switching's outputs (s). dc controls with 4.5V~60V voltage are supplied and operated. Workable in an dc switcher where -40°C~150°C TJ is the -40°C~150°C TJrm. The switching controller is capable of switching at the 105kHz~760kHz position. It is suitable for general dc dc regulator when it is set to Surface Mount. Current Limit, Enable, Frequency Control, Power Good, Soft Start is used for efficient switching control in the dcdc regulator. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. QUAD are the position of the terminal of the switching converters. Various 28 terminations. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. A DC switcher's nominal voltage of 12V is input. LTC3784 can be searched for other relevant dc to dc converter ics. 28 pins are on switching converter. A 60V voltage of DC regulator was detected in the test statistics. In most cases, the output current of the dc dc regulator will be 25A, so note that when you start the project. The duty cycle of the voltage regulator dc to dc can be set to 96 % on power-up or power-down to ensure reliability. DC to DC voltage regulator has the value of OUTPUT VOLTAGE IS ADJUSTABLE UPTO 60V to better satisfy the requirement. The dc to dc voltage regulator belongs to the PolyPhase? series. The maximum input voltage of this dc switcher is 60V, so users must limit the voltage accordingly. Switching controller is necessary to have a supply voltage of 2.3V. At its maximum, the switching converter can output 60V volts.
