LM3679UR-1.5/NOPB Product Details

LM3679UR-1.5/NOPB Overview


optimized performance is achieved by utilizing the Tape & Reel (TR) package in this voltage regulator. In this voltage regulator, 5 terminations are present. As a matter of fact, the type of analog IC that this voltage regulator 12v is equipped with is called SWITCHING REGULATOR. Due to DC DC switching regulator's space saving design, this voltage regulator is available in a 5-XFBGA package. In this case, DC DC switching regulator has 1 outputs configured to it. DC DC switching regulators like this one generate Fixed outputs on their output pins to handle the power management. The voltage regulator 12v fits the Surface Mount mounting hole. In order for it to operate properly, dc to dc voltage regulator's operating temperature should be at -30°C~85°C TA. A DC-DC switching regulator of this type operates at a switching frequency of 3MHz. A dc to dc voltage regulator's minimum input voltage of 2.5V is required for this voltage regulator to operate. The peak reflow temperature of this regulator amounts to 260 to be essentially indestructible. An input voltage of 3.6V is required for switching regulator operation. This voltage regulator is included in the Switching Regulator or Controllers subcategory. LM3679 is a family of voltage regulators that belong to the DC/DC industry. Voltage can be produced at 1.5V volts by voltage regulator. To operate the voltage regulator 12v, 5 pins are required. Ideally this switch regulator should have an output voltage of about 1.5V at the very least. The maximum output current reaches 350mA A to meet the switching regulator operation requirements. DC-DC switching regulator with 5.5V supply voltage. Voltage regulator consumes 1.6mA A of quiescent current without being affected by outside forces. Adjusting voltage regulator reliable performance is ensured based on the minimal supply voltage of 2.5V V. Switching regulators with CURRENT MODE CONTROL IS ALSO POSSIBLE IN PFM CONTROL TECHNIQUE features are highly efficient and stable.
