LTC1159CG-3.3#PBF

DC DC Switching Controllers Overview

The LTC1159CG-3.3#PBF is a synchronous step-down switching regulator controller from Analog Devices, housed in a 20-pin SSOP package. It operates with an input voltage range of 4V to 40V and delivers up to 2A output current. The device features automatic Burst Mode operation to maintain high efficiency at low output currents, achieving up to 95% efficiency. It supports positive or negative output configurations and functions as a DC-to-DC converter.

DC DC Switching Controllers Feature Summary

• Synchronous buck topology for high efficiency
• Automatic Burst Mode operation for light load efficiency
• Supports positive or negative output configurations

DC DC Switching Controllers Applications

• High efficiency synchronous step-down switching regulator circuits
• 12V to -12V 1A converter designs
• Low output current applications requiring maintained efficiency

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates the tube packaging variant compared to #TRPBF tape-and-reel options. Confirm the 20-SSOP package type matches your PCB footprint requirements. Ensure the fixed 3.3V internal reference aligns with your target output voltage needs before ordering.

DC DC Switching Controllers Selection Notes

Select this component when a synchronous buck controller with integrated high-side and low-side drivers is required. It is suitable for applications needing wide input voltage ranges up to 40V. Consider the fixed 3.3V reference if that matches your design; otherwise, other variants in the LTC1159 family may be more appropriate.

DC DC Switching Controllers Part Context

This part belongs to the LTC1159 series of synchronous step-down switching regulator controllers. The series is characterized by its ability to maintain high efficiencies across varying load conditions through automatic Burst Mode operation. It is designed for use in compact power supply solutions requiring robust performance.

DC DC Switching Controllers Replacement Considerations

Check for other LTC1159 variants such as LTC1159CG-5 or LTC1159CG-3.3#TRPBF depending on packaging preference. Verify compatibility with existing control loops and external component selections when substituting.
