Introducing the LTC3407AEMSE Dual-Channel Synchronous Step-Down Regulator

The LTC3407AEMSE is a high-performance, dual-channel, synchronous step-down regulator from Linear Technology. This compact and efficient power management solution is designed to meet the rigorous demands of portable electronic devices. Its advanced design offers a combination of high efficiency, low quiescent current, and a wide input voltage range, making it an ideal choice for battery-powered applications such as smartphones, tablets, and other handheld devices.

Key Features and Benefits:

• Dual Independent Outputs: The LTC3407AEMSE provides two independent output voltages that can be adjusted from 0.8V to VIN, with output current capabilities of up to 600mA for each channel. This flexibility allows designers to power multiple voltage rails in a system with a single compact device.
• Synchronous Operation: Thanks to its synchronous rectification topology, the LTC3407AEMSE achieves high efficiency across a wide range of load currents. This reduces power loss and improves battery life in portable applications.
• Wide Input Voltage Range: With an input voltage range of 2.5V to 5.5V, the LTC3407AEMSE is versatile and can operate from various power sources, including single-cell Li-Ion batteries.
• Low Quiescent Current: The device features a low quiescent current of only 20µA per channel, which is critical for extending battery life in portable devices during standby and light-load conditions.
• Compact Packaging: Housed in a compact 10-lead MSOP package, the LTC3407AEMSE saves valuable board space, which is essential for space-constrained applications.
• Integrated Features: The regulator includes internal soft-start to limit inrush current during startup, a power good status output, and independent shutdown controls for each channel.
