LM2678S-3.3 Product Details

LM2678S-3.3 Overview


As a result of the use of the Tube package, the performance of this voltage regulator is optimized. This harley voltage regulator has 7 terminations. There are two types of analog ICs in this voltage regulator 12v: SWITCHING REGULATOR ICs, which are the ones used in older voltage regulator 12vs. Due to DC DC switching regulator's space saving design, this voltage regulator is available in a TO-263-8, D2Pak (7 Leads + Tab), TO-263CA package. DC DC switching regulator is configured with 1 outputs. There are output pins on this DC DC switching regulator that generate Fixed output. Surface Mount-mounting is compatible with this switching regulator. Operating at -40°C~125°C TJ is the recommended temperature for adjusting voltage regulator's operation. In this voltage regulator 12v, the switching frequency is 260kHz. The voltage regulator can operate with a dc to dc voltage regulator's minimum input voltage of 8V. 40V volts is DC DC switching regulator's maximum input voltage. 235 is essentially indestructible due to DC DC switching regulator's peak reflow temperature. In order to meet the operation requirements,voltage regulator is designed to provide a nominal input voltage of 12V. DC/DC regulators such as this one belong to the LM2678 family of products. Voltage can be produced at 3.3V volts by voltage regulator. In order to operate voltage regulator, there are 7 pins that must be connected. In order for this switching regulator to work properly, the output voltage should be at least 3.3VV. The maximum output current reaches 5A A to meet the switching regulator operation requirements. The switching DC-DC regulator belongs to the SIMPLE SWITCHER? family of electronic voltage regulator 12vs. With a supply voltage of 40V, this harley voltage regulator works. External factors do not affect voltage regulator's consumption of 4.2mA A of quiescent current.
