LT1940EFE#PBF Overview


As a result of the use of the Tube package, the performance of this voltage regulator is optimized. Space savings are achieved by placing this voltage regulator in the 16-TSSOP (0.173, 4.40mm Width) Exposed Pad package. In this case, DC DC switching regulator has 2 outputs configured to it. The adjusting voltage regulator generates Adjustable output. This switching regulator is designed to fit the Surface Mount mounting system. 0°C~70°C TA should be the operating temperature when voltage regulator is operating. This DC-DC switching regulator has a switching frequency of 1.1MHz. Despite its low input voltage, this voltage regulator can operate. The adjusting voltage regulator's output voltage (Min/Fixed) is 1.25V. The output current of 1.4A makes dc to dc voltage regulator feature maximum design flexibility. Voltage regulator's input voltage can reach 25V. DC/DC regulators such as this one belong to the LT1940 family of products. There is a possibility that DC DC switching regulator can give voltage at 19.5V volts. In order to operate voltage regulator, there are 16 pins that must be connected. A 1.4A A maximum output current is required to meet the switching regulator operation requirements. By using the 22V's maximal output voltage, adjusting voltage regulator can operate easily. A high maximum operating temperature 85°C ensures stable operation of switching regulator. Reliability is ensured at minimum DC DC switching regulator's operating temperatures of -40°C. The dc to dc voltage regulator's input voltage must be at least 3.6V in order to work. It is designed to sustain a dc to dc voltage regulator's maximum 25V input voltage. I would like to point out that the voltage regulator 12v has 1 channels.
