LTC1436ACGN-PLL#PBF

DC DC Switching Controllers Overview

The LTC1436ACGN-PLL#PBF is a synchronous buck switching regulator controller manufactured by Analog Devices Inc. It features a fixed frequency architecture with phase-lock loop (PLL) capability for external clock synchronization or frequency modulation to reduce electromagnetic interference. The device drives external N-channel power MOSFETs using Adaptive Power technology, achieving high efficiency up to 400kHz. It operates with an input voltage range of 5.5V to 28V and provides a single positive output. The IC is housed in a 24-pin SSOP package and supports control features including enable, power-on reset, and soft start.

DC DC Switching Controllers Feature Summary

• Synchronous buck topology with Adaptive Power output stage for optimized efficiency
• Phase-lock loop architecture allowing synchronization to external clocks or frequency spreading
• Integrated control functions including enable, power-on reset, and soft start

DC DC Switching Controllers Applications

• Industrial distributed power systems
• Telecommunications infrastructure equipment
• Point-of-load regulation modules

DC DC Switching Controllers Procurement Notes

Verify the exact suffix #PBF indicates lead-free compliance and RoHS status. Confirm the package type matches the design requirements as variations exist within the family. Check current availability status as distribution channels may list discontinued or limited stock items. Ensure the operating temperature grade aligns with the application environment specifications.

DC DC Switching Controllers Selection Notes

Select this component when precise frequency synchronization or EMI reduction via frequency modulation is required. The PLL feature distinguishes it from standard fixed-frequency variants. Consider the 24-SSOP package constraints for PCB layout. Evaluate the need for external MOSFETs as the controller does not integrate power switches internally.

DC DC Switching Controllers Part Context

This part belongs to the LTC1436A/LTC1437A family of high-efficiency synchronous step-down controllers. The 'ACGN' designation specifies the commercial temperature range and SSOP package. The '-PLL' suffix denotes the inclusion of the phase-lock loop interface. It serves as a core control element in DC-DC conversion designs requiring flexible switching frequency management.

DC DC Switching Controllers Replacement Considerations

LTC1436AIGN-PLL#PBF is a direct substitute offering the same functionality in an industrial temperature grade variant.
