LTC3407EMSE

The LTC3407EMSE is a dual, high-efficiency, step-down DC/DC converter designed to provide two independently regulated outputs. It is commonly used in portable electronic devices due to its compact size and efficient performance. The converter operates from an input voltage range of 2.5V to 5.5V, suitable for single-cell Li-ion batteries or other low-voltage power sources.
The device features two synchronous buck regulators, each capable of delivering up to 600mA of output current. The switching frequency is internally set at 1.5MHz, allowing for the use of small inductors and capacitors, which results in a compact solution footprint. The LTC3407EMSE provides high efficiency over a wide load range due to its automatic Burst Mode operation, which reduces power consumption during light loads.
Other features include independent soft-start for each channel, 100% duty cycle operation for low dropout, and thermal shutdown protection. The LTC3407EMSE is packaged in a thermally enhanced, low-profile MSOP-10 package, making it suitable for space-constrained applications.
