LTC1436ACGN#PBF

DC DC Switching Controllers Overview

The LTC1436ACGN#PBF is a high-efficiency, low-noise synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 5.5V to 28V and provides a positive output via a buck topology. The device features a fixed switching frequency of 400kHz and supports up to 99% duty cycle. It is housed in a 24-SSOP package and includes control features such as enable, power-on reset, and soft start. The IC is designed for applications requiring precise regulation and low electromagnetic interference.

DC DC Switching Controllers Feature Summary

• Synchronous rectification architecture ensures high conversion efficiency across varying load conditions.
• Integrated low-noise design minimizes output ripple and switching harmonics for sensitive analog circuits.
• Programmable soft-start and power-on reset capabilities facilitate controlled startup sequences.
• External clock synchronization allows frequency alignment to reduce system-wide EMI.

DC DC Switching Controllers Applications

• Telecommunications infrastructure power distribution
• Industrial control systems requiring stable DC rails
• Portable equipment with battery-powered inputs

DC DC Switching Controllers Procurement Notes

Verify the complete part number including the suffix #PBF to ensure lead-free compliance and RoHS status. Confirm the package type is 24-SSOP and check the manufacturer's current lifecycle status, as availability may vary. Ensure the operating temperature range meets your specific environmental requirements before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component when a single-output buck converter with low noise characteristics is required. It is suitable for designs needing a wide input voltage range up to 28V. Consider the 400kHz switching frequency for balancing component size and efficiency. Verify that the 24-SSOP package fits your PCB layout constraints.

DC DC Switching Controllers Part Context

This part belongs to the LTC1436 family of synchronous step-down regulators. It shares functional similarities with other variants like the LTC1436AIGN-PLL but differs in package and specific electrical tolerances.
