LT3640IFE#PBF Product Details
LT3640IFE#PBF Overview
optimized performance is achieved by utilizing the Tube package in this voltage regulator. Throughout this voltage regulator, there are 28 terminations. There are two types of analog ICs in this voltage regulator 12v: DUAL SWITCHING CONTROLLER ICs, which are the ones used in older voltage regulator 12vs. The space-saving 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package is available for this voltage regulator. The voltage regulator 12v has 2 outputs. The adjusting voltage regulator generates Adjustable output. As the name implies, this voltage regulator 12v is designed for mounting on a Surface Mount bracket. During switching regulator operation, the operating temperature should remain at -40°C~125°C TJ. This voltage regulator 12v reaches a switching frequency of 500kHz~2MHz. The regulator is capable of operating with a dc to dc voltage regulator's minimum input voltage of 2.5V. As shown in the table below, adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.6V 1.265V. A maximum design flexibility is provided by the 1.1A 1.3A output current of voltage regulator. There is a maximum input voltage of 35V for this voltage regulator 12v. A regulator voltage's peak reflow temperature amounts to 260 being indestructible. The voltage regulator 12v is designed to provide a nominal input voltage of 12V for operation. In terms of category, this voltage regulator 12v falls into the Switching Regulator or Controllers category. In the particular voltage regulators, the LT3640 family is represented. A voltage of 3.3V volts can be generated by DC DC switching regulator. There are 28 pins used for switching regulator operation. By using the 33.97V's maximal output voltage, adjusting voltage regulator can operate easily. By adding the PFM CONTROL TECHNIQUE ALSO POSSIBLE feature, this harley voltage regulator is more efficient and stable.
