LTC3633EUFD#PBF - High Efficiency, Dual Channel Monolithic Synchronous Step-Down Regulator

The LTC3633EUFD#PBF is a high-performance, dual channel monolithic synchronous step-down regulator from Linear Technology, designed to deliver efficient power management for a variety of applications. This compact and versatile component operates over a wide input voltage range from 4V to 20V, making it suitable for systems powered from a variety of sources including single-cell Li-Ion, multiple Alkaline/NiMH cells, and fixed 5V or 12V power rails.

Each of the two independent channels can deliver up to 3A of continuous output current with peak efficiency as high as 95%. The regulator's high efficiency is maintained over a wide output current range by utilizing low RDS(ON) internal switches and a constant frequency/controlled on-time architecture that provides fast transient response and excellent loop stability.

The LTC3633EUFD#PBF is packed with features to ensure the stability and reliability of your power supply design. It includes independent power good signals, and a selectable Burst Mode operation, which is designed to improve efficiency at light loads. Additionally, the device is capable of 100% duty cycle operation for low dropout performance, which is essential for battery-powered systems.

This regulator is available in a 24-lead 4mm x 5mm QFN package, which provides a compact solution with a minimal footprint. This, combined with its high switching frequency of up to 4MHz, allows the use of small, low-cost capacitors and inductors, further reducing the space and cost of the overall power supply solution.

The LTC3633EUFD#PBF also includes a tracking capability, ensuring both outputs can be accurately sequenced. Other features include overvoltage protection, overcurrent protection, and thermal shutdown, which safeguard your system against adverse operating conditions. With its robust feature set, the LTC3633EUFD#PBF is ideal for a variety of demanding applications, including portable devices, automotive power supplies, and distributed power systems.
