LTC1437ACG#PBF

DC DC Switching Controllers Overview

The LTC1437ACG#PBF is a high-efficiency, low noise synchronous buck switching regulator controller manufactured by Analog Devices Inc. It operates within an input voltage range of 3.5V to 30V and supports a maximum switching frequency of 400kHz. The device features a 28-SSOP package and includes integrated control characteristics such as enable functionality, power-on reset, and soft-start capabilities. Designed for positive output configurations, it utilizes a single output stage with a maximum duty cycle of 99%.

DC DC Switching Controllers Feature Summary

• Synchronous rectification architecture for enhanced efficiency
• Integrated soft-start and power-on reset mechanisms
• Low operating supply current for energy conservation
• Shutdown mode capability for power management

DC DC Switching Controllers Applications

• Portable battery-powered equipment
• Distributed power systems
• Industrial control applications

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when sourcing samples or production units. Confirm that the AC grade meets the required commercial temperature range specifications for your application environment. Ensure compatibility with the 28-SSOP footprint during PCB layout finalization.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring a compact synchronous buck solution with low quiescent current. Consider the 400kHz maximum frequency limit when optimizing external inductor and capacitor values. Evaluate the 3.5V minimum input voltage constraint against your system's lowest operating rail conditions.

DC DC Switching Controllers Part Context

This part belongs to the LTC1437 family of high-performance synchronous step-down controllers. It shares architectural similarities with other Analog Devices regulators but is distinct in its specific pinout and control feature set. The AC grade denotes commercial temperature performance standards defined by the manufacturer.

DC DC Switching Controllers Replacement Considerations

LTC1437AIG#TR is a compatible alternative offering identical electrical performance with tape-and-reel packaging instead of tubes.
