LTC3547BEDDB#TRMPBF Dual Channel Buck Regulator

The LTC3547BEDDB#TRMPBF is a high-performance, dual-channel synchronous buck regulator from Linear Technology, designed to deliver efficient power management for a variety of applications. This compact and versatile regulator is capable of providing two independent output voltages from a single input, making it an ideal choice for space-constrained applications that require multiple regulated voltages.

Each channel of the LTC3547BEDDB#TRMPBF is capable of delivering up to 600mA of continuous output current with a wide input voltage range from 2.5V to 5.5V. This makes it perfectly suited for portable devices powered by Li-Ion/Polymer batteries, as well as 3.3V or 5V rails. The high switching frequency of up to 2.25MHz allows the use of small, low-cost capacitors and inductors, further reducing the overall solution footprint on the PCB.

One of the key features of this regulator is its high efficiency, which can reach up to 95%. This is achieved through the use of low RDS(ON) internal switches and a constant frequency, current mode architecture. The LTC3547BEDDB#TRMPBF also includes a Burst Mode operation, which provides excellent efficiency at low output currents and ensures extended battery life in portable applications.

In addition to its high efficiency, the LTC3547BEDDB#TRMPBF offers a host of protection features to ensure the safety and reliability of the end application. These include over-temperature protection, over-current protection, and a power good status output for each channel. The device also features internal soft-start to limit inrush current during startup, further enhancing system stability.

The LTC3547BEDDB#TRMPBF comes in a 10-lead DFN (3mm x 3mm) package with a low profile, which is RoHS compliant and suitable for automated assembly processes. It is available in tape and reel form, denoted by the TRMPBF suffix, for ease of manufacturing and inventory management.

With its dual output capability, high efficiency, and compact size, the LTC3547BEDDB#TRMPBF is an excellent power management solution for applications such as handheld devices, portable media players, digital cameras, and other battery-operated electronics that require efficient and reliable power delivery.
