LTC3633EUFD#TRPBF Dual Channel, High Efficiency, 3A, 15V Monolithic Synchronous Step-Down Regulator

The LTC3633EUFD#TRPBF is a high-performance, dual-channel monolithic synchronous buck regulator from Linear Technology, which is now part of Analog Devices. This component is designed to deliver up to 3A of continuous output current per channel, with a wide input voltage range of 4V to 15V, making it an excellent choice for a variety of demanding applications.

Featuring a high efficiency design, the LTC3633EUFD#TRPBF incorporates internal switches with low on-resistance to minimize power loss and heat generation. The regulator operates at a selectable fixed frequency between 500kHz and 4MHz, which allows the use of small, low-cost inductors and ceramic capacitors, resulting in a compact power supply solution. Additionally, the device offers the option of a phase-lockable frequency (PLL) for noise-sensitive applications where it is crucial to minimize interference with other system components.

The LTC3633EUFD#TRPBF has a range of built-in protection features to ensure the safety and reliability of the system. These include overvoltage protection, overcurrent protection, and thermal shutdown. The device also features independent track/soft-start capability for each channel, allowing for controlled startup and sequencing of multiple power rails.

This regulator comes in a 28-lead (4mm × 5mm) QFN package, which is designed for a compact footprint and optimized thermal performance. Its exposed pad enhances thermal dissipation, ensuring stable operation even under high load conditions.

With its robust feature set and high efficiency, the LTC3633EUFD#TRPBF is well-suited for a variety of applications, including telecommunications, industrial systems, and portable electronics. Its ability to provide stable, dual-channel power conversion makes it a versatile choice for designers looking to simplify their power management solutions.

Whether you're developing a new product or optimizing an existing design, the LTC3633EUFD#TRPBF from Linear Technology provides the performance, reliability, and flexibility needed to meet the stringent requirements of modern electronic systems.
