Description

LT8640IUDC#TRPBF Overview
This harley voltage regulator utilizes the Tape & Reel (TR) package for optimized performance. Space-saving 20-WFQFN, 18 Leads, Exposed Pad packages are available for this harley voltage regulator. A total of 1 outputs are configured in this voltage regulator. This DC DC switching regulator generates Adjustable output on its output pins. As the name implies, this voltage regulator 12v is designed for mounting on a Surface Mount bracket. Voltage regulators should be operated at -40°C~125°C TJ temperature while operating. A DC-DC switching regulator such as this one switches at 210kHz~2MHz. Voltage regulators like this one can operate at least with 3.4V as the dc to dc voltage regulator's minimum input voltage. It is evident from the table below that adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.97V. As a result of the 5A output current, voltage regulator offers maximum flexibility in design. DC/DC regulators such as this one belong to the LT8640 family of products. Voltage of voltage regulator can be delivered at 41.9V volts. 18 pins are used for switching regulator operation. As a general rule, this voltage regulator 12v should keep its output voltage at least at 970mV. There is a maximum output voltage of 42V from this voltage regulator 12v.
