Vue d'ensemble

Description

The LTC3407EMSE-2 is a dual, high-efficiency, synchronous step-down DC/DC converter. Designed by Linear Technology (now part of Analog Devices), it is optimized for portable applications that require high efficiency at low output currents. The device operates from an input voltage range of 2.5V to 5.5V, making it suitable for single Li-Ion battery-powered applications.
Key features include a programmable switching frequency of up to 3MHz, allowing for the use of tiny, low-cost capacitors and inductors. The LTC3407EMSE-2 delivers two regulated output voltages, with each channel capable of supplying up to 600mA of output current. It automatically transitions between Burst Mode® operation at light loads to maintain high efficiency and PWM mode for lower noise at higher loads.
The LTC3407EMSE-2 also includes a power saving shutdown mode, soft-start capability, and short-circuit protection. It is available in a thermally enhanced, low-profile MSOP-10 package, making it ideal for compact portable devices. Overall, the LTC3407EMSE-2 is a versatile solution for efficient power management in portable electronics.

Features

The LTC3407EMSE-2 is a dual, high-efficiency, step-down DC/DC converter designed for portable applications. It features a wide input voltage range of 2.5V to 5.5V, making it suitable for single-cell lithium-ion batteries and other low-voltage sources. The device provides two independent outputs, each capable of delivering up to 600mA of continuous current.
Key features include:
- High efficiency of up to 95% through synchronous rectification.
- A low quiescent current of about 20μA per regulator in Burst Mode operation, extending battery life.
- Fast switching frequency of 1.5MHz, allowing the use of small external components.
- Internal compensation simplifies circuit design.
- Output voltage can be set as low as 0.6V.
- Automatic transition between Burst Mode operation at light loads and PWM at higher loads for optimal efficiency.
- Soft-start feature to minimize inrush current during startup.
- Current-mode control for fast transient response and stability.
- Shutdown current is less than 1μA, reducing power consumption when the device is off.
- Compact 10-pin MSOP package for space-constrained applications.
These features make the LTC3407EMSE-2 ideal for power-efficient, space-sensitive applications like smartphones, PDAs, and other portable electronic devices.
