DC DC Switching Controllers datasheet and documents for LTC3727EG#TRPBF
DC DC Switching Controllers Overview
The LTC3727EG#TRPBF is a high-performance dual synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4V to 30V and supports output voltages from 800mV to 14V with up to 25A output current capability per channel. The device utilizes a constant frequency current mode architecture with a switchable frequency between 255kHz and 530kHz, allowing for phase-locking up to 550kHz. Packaged in a 28-SSOP format, it functions across a temperature range of -40°C to +85°C.
DC DC Switching Controllers Feature Summary
- Dual-channel architecture enables out-of-phase operation to minimize input capacitor ESR power loss and noise
- Supports all N-channel synchronous power MOSFET stages for efficient power conversion
- Features integrated soft-start, enable control, and power good monitoring capabilities
DC DC Switching Controllers Applications
- Industrial distributed power systems
- Telecommunications infrastructure power supplies
- Point-of-load regulation for digital signal processors
DC DC Switching Controllers Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the EG variant corresponds to the specified SSOP package and commercial/industrial temperature rating. Ensure compatibility with existing PCB footprints for the 28-pin SSOP configuration during procurement planning.
DC DC Switching Controllers Selection Notes
Select this component for designs requiring two independent regulated outputs from a single controller IC. It is suitable for applications needing high efficiency through synchronous rectification and low noise via phase-skewed operation. Consider the 28-SSOP package constraints regarding thermal dissipation and board space availability.
DC DC Switching Controllers Part Context
This part belongs to the LTC3727 family of dual synchronous buck controllers. It shares architectural similarities with other high-current regulators but is distinct in its specific pinout and frequency range options. The EG designation identifies the package type and operating temperature grade within the manufacturer's portfolio.
DC DC Switching Controllers Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence carefully if considering alternative dual-buck controllers.
