LTC1929IG-PG#PBF

DC DC Switching Controllers Overview

The LTC1929IG-PG#PBF is a dual-phase synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4V to 36V and supports fixed frequencies between 150kHz and 300kHz. The device features current-mode control for precise load sharing, ±1% output voltage accuracy, and true remote sensing via a differential amplifier. It includes an OPTI-LOOP compensation system to enhance transient response and offers adjustable soft-start current ramping with internal foldback short-circuit protection.

DC DC Switching Controllers Feature Summary

• Dual-phase single output controller architecture that reduces required input capacitance and power supply induced noise.
• Current-mode control mechanism ensures accurate current sharing between phases.
• Integrated differential amplifier provides true remote sensing capabilities for improved regulation.

DC DC Switching Controllers Applications

• High-efficiency point-of-load (POL) conversion systems
• Industrial equipment requiring stable low-voltage power distribution
• Telecommunications infrastructure power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'PG' indicates the inclusion of a Power Good output voltage monitor function as distinct from the standard LTC1929 variant. Confirm package integrity for the SSOP-28 form factor upon receipt. Ensure compatibility with the selected operating frequency range during initial circuit validation.

DC DC Switching Controllers Selection Notes

Select this component when dual-phase operation is required to minimize input ripple and thermal stress in high-current applications. The integrated OPTI-LOOP compensation simplifies loop stability design across wide input voltage ranges. Consider the PG variant if system status monitoring is necessary without external logic components.
