MAX1945REUI+ Overview


optimized performance is achieved by utilizing the Tube package in this voltage regulator. In this voltage regulator, 28 terminations are present. There are two types of analog ICs on this voltage regulator. The first type is a SWITCHING REGULATOR-type IC. There is a 28-TSSOP (0.173, 4.40mm Width) Exposed Pad package available for this voltage regulator, as DC DC switching regulator is space-saving. There are 1 outputs configured on the voltage regulator. Adjusting voltage regulator's output pins generate Adjustable (Programmable) output. A Surface Mount mounting is required for this switching regulator. Voltage regulators should be operated at -40°C~85°C TA temperature while operating. There is a switching frequency of 400kHz~1.2MHz for this voltage regulator 12v. As shown in the table below, adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.8V 1.8V 2.5V. Its 260 peak reflow temperature makes this regulator essentially indestructible. An input voltage of 3.3V is required for switching regulator operation. This voltage regulator is included in the Switching Regulator or Controllers subcategory. DC/DC regulators of this type are part of the MAX1945 family of voltage regulator 12vs. Voltage can be produced at 2.5V volts by voltage regulator. There are 28 pins used for switching regulator operation. There should be at least a 2.5V volt output voltage for this switching regulator in order to make it work properly. For switching regulator maximum operation, dc to dc voltage regulator delivers 6A A. On the basis of 4.68V's maximal output voltage, DC DC switching regulator can be operated easily. As a result, it is able to provide adjusting voltage regulator a maximum output voltage of 4.68V. This DC-DC switching regulator operates from a supply voltage of 5.5V. In order to ensure reliable performance, the dc to dc voltage regulator's minimum supply voltage is 2.6V volts. There is a maximum input voltage of 5.5V that DC DC switching regulator can operate from. A frequency of 1MHz enables dc to dc voltage regulator to maintain high accuracy.
