LTC1702ACGN#PBF

DC DC Switching Controllers Overview

The LTC1702ACGN#PBF is a dual synchronous switching regulator controller designed for high-efficiency power conversion. It operates at a fixed frequency of 550kHz and utilizes a constant frequency current mode architecture. The device supports two-phase operation, enabling the interleaving of phases to reduce input and output ripple currents. It features an internal oscillator and requires no external sense resistor for current sensing. The controller accepts an input voltage range starting from 5V and includes comprehensive protection features such as overvoltage lockout and thermal shutdown.

DC DC Switching Controllers Feature Summary

• Dual-channel control for synchronized two-phase buck regulation
• Internal current sensing eliminates the need for external sense resistors
• Fixed 550kHz switching frequency with phase interleaving capability
• Constant frequency current mode architecture for stable transient response

DC DC Switching Controllers Applications

• High-density point-of-load (POL) DC/DC converters
• Multi-phase power supplies for processors and FPGAs
• Industrial equipment requiring efficient step-down regulation
• Telecommunications infrastructure power systems

DC DC Switching Controllers Procurement Notes

Verify the suffix #PBF indicates lead-free compliance when sourcing. Confirm the package type matches the required footprint, specifically the 24-lead SSOP. Ensure the grade 'A' meets the specified temperature range requirements for your application environment. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

DC DC Switching Controllers Selection Notes

Select this component when designing multi-phase power architectures that demand reduced ripple and improved transient performance. It is suitable for applications requiring precise current sharing without external sensing components. Consider the 550kHz frequency trade-off between size and efficiency. Ensure the controller's input voltage range aligns with the system's supply rails.

DC DC Switching Controllers Part Context

This component belongs to Linear Technology's family of synchronous switching regulators. It complements other controllers by offering dual-phase management in a compact package. The device is part of the broader portfolio aimed at optimizing power density in modern electronic systems. It shares architectural similarities with single-phase counterparts but adds interleaving capabilities.

DC DC Switching Controllers Replacement Considerations

Direct substitutes may include other dual-phase synchronous controllers from Analog Devices or compatible manufacturers. Verify pin compatibility and control loop stability before substitution. Check if alternative parts support the same 550kHz frequency and current mode architecture. Ensure thermal and electrical specifications meet or exceed the original design requirements.
