The LT3680’s 4.6A internal switch can deliver up to 3.5A of continuous output current at voltages as low as 0.79V. The LT3680’s Burst Mode operation ensures ultralow quiescent current, well suited for applications such as automotive or telecom systems, which demand always-on operation and optimum battery life. Switching frequency is user programmable from 250kHz to 2.4MHz, enabling the designer to optimize efficiency while avoiding critical noise-sensitive frequency bands. The LT3680’s thermally enhanced MSOP-10E package and high switching frequency keep external inductors and capacitors small, providing a compact, thermally efficient footprint. Other features include external synchronization (from 250kHz to 2MHz), a power good flag and soft-start capability.
The LT3680HMSE is priced starting at $5.35 each in 1,000-piece quantities and is available from stock. For more information, visit www.linear.com.
