LTC3448EDD#PBF Overview
It is designed to provide optimal performance by utilizing the Tube package. There are 8 terminations in this voltage regulator. 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 8-WFDFN Exposed Pad package. A total of 1 outputs are configured in this voltage regulator. On the output pins of this DC DC switching regulator, there is a Adjustable output generated. Surface Mount-mount switching regulator. When operating, adjusting voltage regulator's operating temperature should be kept at -40°C~85°C TA. In this voltage regulator 12v, the switching frequency is 1.5MHz~2.25MHz. Regulator 2.5V can operate with dc to dc voltage regulator's minimum input voltage 2.5V. The output voltage (Min/Fixed) of this voltage regulator 12v is 0.6V. The output current of 600mA makes dc to dc voltage regulator feature maximum design flexibility. There is a voltage regulator maximum input voltage of 5.5V. As a result of the 260 peak reflow temperature, this regulator is essentially indestructible. In order to meet the operation requirements,voltage regulator is designed to provide a nominal input voltage of 3.6V. In terms of category, this voltage regulator 12v falls into the Switching Regulator or Controllers category. This DC/DC regulator belongs to the LTC3448 family. A voltage of 5.2V volts can be generated by DC DC switching regulator. For switching regulator operation, 8 pins are used.
