DC DC Switching Controllers datasheet and documents for LTC1735IS-1#PBF

LTC1735IS-1#PBF

DC DC Switching Controllers Overview

The LTC1735IS-1#PBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 3.5 V to 36 V and delivers up to 20 A of output current. The device supports adjustable output voltages from 800 mV to 6 V. Key electrical specifications include a typical quiescent current of 450 uA, a fixed switching frequency of 300 kHz, and a load regulation of -0.1%. It functions reliably across an operating temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

Integrates high-side and low-side power MOSFETs for efficient synchronous rectification in a compact package.
Features a constant-frequency current mode control architecture that ensures rapid transient response and inherent cycle-by-cycle current limiting.
Includes comprehensive protection mechanisms such as thermal shutdown, undervoltage lockout, and soft-start functionality.

DC DC Switching Controllers Applications

Point-of-load regulation for digital signal processors and field-programmable gate arrays
Power distribution systems in industrial equipment and telecommunications infrastructure
Battery-powered portable devices requiring efficient voltage conversion

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free packaging compliant with RoHS standards. Confirm the IS-1 variant matches the required SOIC-16 package and commercial/industrial temperature grade. Cross-reference the manufacturer datasheet to ensure all electrical parameters align with system requirements before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component when a single-channel, high-current buck converter is needed for inputs up to 36 V. The 300 kHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Ensure the thermal design accommodates the power dissipation associated with 20 A loads, considering the SOIC-16 package limitations.

DC DC Switching Controllers Part Context

This part belongs to the LTC1735 family of synchronous step-down regulators designed for high-efficiency power management. It serves as a robust solution for converting higher bus voltages to lower logic levels. The IS-1 designation specifies the pin-compatible variant optimized for standard surface-mount assembly processes.
