TPS43351QDAPRQ1 Product Details

TPS43351QDAPRQ1 Overview


It comes in the 38-PowerTSSOP (0.240, 6.10mm 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 Tape & Reel (TR) solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 4V~40V. Qualified to work in an dc switcher with -40°C~125°C TJ. The switching controller can be switched at 150kHz~600kHz. dc dc regulators can be carried out with Surface Mount. Enable, Frequency Control, Power Good, Soft Start, Tracking 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 38 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input of 13V. TPS43351 can be searched for other relevant dc to dc converter ics. In total, switching converter has 38 pins. Switching converter type is specifically Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 4V. Statistically, DC regulator outputs 5V volts. In most cases, the output current of the dc dc regulator will be 3A, so note that when you start the project. Power-up and power-down reliability is ensured voltage regulator dc to dc by setting the maximum duty cycle to 98.75 %. DC switcher's Surface Mount qualifies it for most applications and prototypes. 600kHz is the maximum frequency of this dc regulators. For better satisfaction, the value of DC to DC voltage regulator is OPERATES IN ADJUSTABLE MODE FROM 0.9 TO 11V, ALSO HAS CONTROL TECHNIQUE OF PFM. For safe and reliable operation in a circuit, voltage regulator dc to dc is suggested that users apply 40V. A dc to dc voltage regulator in the Automotive, AEC-Q100 series, it belongs to this family. Dormant dc switchings use 30μA.
