LT1339CN#PBF

Overview

The LT1339CN#PBF is a high-power synchronous current-mode switching regulator controller manufactured by Analog Devices Inc. It is designed to drive dual N-channel MOSFETs, providing a complete single-IC solution for step-down DC/DC converter applications. The device operates at a fixed switching frequency of 150 kHz and supports an input voltage range suitable for various industrial and automotive power supplies. Packaged in a 20-pin PDIP, it integrates essential control functions including slope compensation and soft-start capabilities to ensure stable operation under heavy load conditions.

Feature Summary

Integrates high-power synchronous current-mode control architecture
Drives dual N-channel MOSFETs for efficient step-down conversion
Includes built-in slope compensation for stability
Features integrated soft-start functionality

Applications

Automotive power supply systems
Industrial point-of-load converters
High-current DC/DC step-down modules

Procurement Notes

Verify the ordering suffix #PBF confirms lead-free compliance and tube packaging format. Ensure the CN suffix indicates commercial temperature grade suitability for your specific environmental requirements. Cross-reference the manufacturer's latest datasheet revision to confirm pinout consistency and electrical specifications before finalizing procurement orders.

Selection Notes

Select this component when designing synchronous buck converters requiring integrated control without external driver complexity. The fixed 150 kHz frequency allows for optimized passive component sizing. Consider the 20-pin PDIP package constraints for thermal management and PCB layout space compared to surface-mount alternatives.

Part Context

This part belongs to the LT1339 family of high-performance switching regulators. It represents a transition from Linear Technology to Analog Devices following corporate acquisition. The CN variant specifically denotes the commercial temperature range operating specification within the broader product line.
