BD8641EFV-E2 Product Details

BD8641EFV-E2 Overview

This harley voltage regulator utilizes the Tape & Reel (TR) package for optimized performance. During the development of this harley voltage regulator, 20 terminations were made. Space savings are achieved by placing this voltage regulator in the 20-VSSOP (0.173, 4.40mm Width) Exposed Pad package. A total of 1 outputs are configured in this voltage regulator. ICs such as this voltage regulator are capable of generating Adjustable outputs through their output pins. This switching regulator is designed to fit the Surface Mount mounting system. Operating at -40°C~85°C TA is the recommended temperature for adjusting voltage regulator's operation. This voltage regulator 12v reaches a switching frequency of 250kHz~2.3MHz. As shown in the table below, adjusting voltage regulator's output voltage (Min/Fixed) is equal to 0.8V. In terms of category, this voltage regulator 12v falls into the Switching Regulator or Controllers category. As a member of the BD8641 family of DC/DC regulators, this is a DC/DC regulator. The voltage DC DC switching regulator can provide is up to 5.5V volts. For switching regulator operation, 20 pins are used. This voltage regulator 12v should be configured with an output voltage that is at least 800mV. The maximum output current reaches 3A A to meet the switching regulator operation requirements. There is a maximum output voltage of 5.5V from this voltage regulator 12v. Switching regulators operate at 3.3V supply voltages. Adjusting voltage regulator reliable performance is ensured based on the minimal supply voltage of 3V V. As long as the supply voltage is greater than 5.5V, the voltage regulator 12v will operate correctly. A frequency of 2.3MHz enables dc to dc voltage regulator to maintain high accuracy.
