Tổng quan
Description
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.
Equivalent
1. TPS62420 from Texas Instruments
2. MAX1555 from Maxim Integrated (for similar applications, though it's a single-output version)
3. AP6502 from Diodes Incorporated (single-channel solution)
4. ISL9301 from Renesas Electronics (dual-channel with similar specs)
Ensure compatibility by comparing specific electrical characteristics and pin configurations. Always consult the datasheets for precise matching.
Features
Key features include a low quiescent current of approximately 30µA, maximizing battery life, and a high switching frequency of up to 3MHz, which enables the use of small external components. The LTC3407EMSE incorporates a power-saving Burst Mode operation to enhance efficiency at light loads. It also includes internal compensation, soft-start, and output overvoltage protection, ensuring robust performance. The device is housed in a compact 10-lead MSOP package, making it suitable for space-constrained applications. Overall, the LTC3407EMSE is designed to provide efficient power conversion with minimal external components, making it ideal for portable electronics.
