LT3791EFE-1 Overview
In the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller meets most application requirements. The dc motor controller is adquate to generate for 2 outputs. Packaged in solid enclosures, this pmic has a Tube rating. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with 4.7V~60V voltage are supplied and operated. Worked in an dc switcher with a -40°C~125°C rating. Switching can be done at 200kHz~700kHz with this switching controller. The Surface Mount value makes it suitable for general dc dc regulator. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Soft Start. SWITCHING REGULATOR analog IC connects the switch converters. The switching converters's terminals (s) are designed at DUAL. An array of 38 terminations of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis 12V volts. An input voltage of 4.7V is the minimum required for the dc dc voltage regulator. DC regulator outputs 5V voltage according to the test statistics. The dc to dc regulator can only accept 60V input voltage.
