LTC1430ACGN#PBF

Special Purpose Regulators Overview

The LTC1430ACGN#PBF is a high-power buck switching regulator controller from Analog Devices. It operates with an input voltage range of 3.6V to 13V and delivers up to 450mA of output current. The device utilizes current-mode control for fast transient response and includes features such as soft-start, frequency synchronization, and cycle-by-cycle current limiting. Packaged in a 16-lead SSOP, it supports operation temperatures from -40°C to +85°C.

Special Purpose Regulators Feature Summary

• Current-mode control architecture for rapid load transient handling
• Integrated soft-start capability to limit inrush current
• Frequency synchronization pin for noise reduction in multi-unit systems
• Cycle-by-cycle current limiting protects against short circuits

Special Purpose Regulators Applications

• Point-of-load regulation for digital signal processors
• Power supply stages for communication equipment
• Embedded system voltage conversion
• Industrial control board power distribution

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'ACGN' matches the required temperature grade and package variant. Confirm RoHS compliance status via the manufacturer datasheet. Check lead times due to potential limited availability. Ensure ordering documentation references the '#PBF' designation for lead-free assembly requirements.

Special Purpose Regulators Selection Notes

Select this component when a compact synchronous or non-synchronous buck solution is needed with integrated control. Evaluate the 450mA current limit against peak load demands. Consider the external MOSFET selection based on the controller's drive capabilities and thermal constraints within the 16-SSOP footprint.

Special Purpose Regulators Part Context

This part belongs to the LTC143x series of switching regulators designed for space-constrained applications. It complements other Analog Devices power management solutions by providing a complete control loop in a small outline package, suitable for replacing discrete PWM controller designs.

Special Purpose Regulators Replacement Considerations

Direct substitutes include the LTC1430IGN#PBF for commercial temperature range variants. Verify pin compatibility and control loop stability when transitioning between different temperature grades or package options within the same family.
