LT3757 / LT3758 wide input range DC-C controller (Li

LT3757 / LT3758 DC / DC Controller (LINEAR) for Wide Input Range LT3757 and LT3758 H-class and MP versions, these two devices are DC / DC controllers with wide input range for boost, reverse excitement, SEPIC, and negative output power applications. These devices have two internal voltage feedback error amplifiers and reference voltages that produce positive or negative stable output voltages. These H-class and MP-level versions are tested to ensure in the range of work junction temperatures from -40 ° C to 150 ° C and -55 ° C to 125 ° C. The LT3757 works within the input voltage range of 2.9V to 40V, while the LT3758 works within 5.5V to 100V input voltage range. These devices have achieved high efficiency of up to 96%, which is ideal for industrial, automotive, military, medical and telecom applications. The designer can select a variety of inductors and capacitors to optimize size, performance, and cost of the designer to optimize size, performance, and cost within the programmable fixed frequency or synchronous operating frequency range. The fixed frequency, current mode control can be stabilized within the wide power source and the output voltage range, and the full ceramic capacitor design can achieve smaller solution size. Other features include programmable soft start, input undervoltage lock, output overvoltage, and overcurrent protection. The two levels of versions have been supplied, and the heat-resistant enhanced MSOP-10 package is adopted. Purchase at 1,000 pieces, each H-level device price is $ 2.56, and the price of each MP level is $ 5.98.
