LTC3737EGN#TRPBF

DC DC Switching Controllers Overview

The LTC3737EGN#TRPBF is a dual two-phase, synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.75V to 9.8V and provides two independent outputs with current capabilities of 3A and 2.5A respectively. The device utilizes a fixed frequency current mode architecture with a switching frequency of 550kHz. It features output tracking, soft start, and clock synchronization. The component is housed in a 24-lead SSOP package and is rated for operation between -40°C and +85°C.

DC DC Switching Controllers Feature Summary

• Dual two-phase synchronous buck controller architecture
• Integrated output tracking capability for sequential power management
• Fixed 550kHz constant frequency current mode control
• Clock synchronization input for system-wide timing alignment

DC DC Switching Controllers Applications

• Evaluation board DC664A demonstration platform
• Multi-rail server and telecom power distribution systems
• Industrial equipment requiring synchronized power sequencing
• Embedded systems needing compact dual-output regulation

DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm the SSOP-24 package variant matches your PCB footprint requirements. Ensure compatibility with the intended input voltage range of 2.75V to 9.8V for your specific application design constraints.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring two isolated or non-isolated low-voltage rails from a single higher voltage source. The integrated tracking feature simplifies power-up sequences compared to using separate controllers. Consider the 550kHz switching frequency for balancing efficiency and passive component size against noise sensitivity requirements.

DC DC Switching Controllers Part Context

This part belongs to the LTC3737 family of dual-channel synchronous buck controllers. It shares architectural similarities with other Linear Technology regulators but is distinct in its specific pinout and dual-channel configuration. The EGNSuffix denotes the commercial temperature grade and SSOP package type.

DC DC Switching Controllers Replacement Considerations
