LTC1142CG#TRPBF

DC DC Switching Controllers Overview

The LTC1142CG#TRPBF is a dual high-efficiency synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates within an input voltage range of 3.5 V to 20 V and provides two independent outputs, typically configured for 3.3 V and 5 V rails. Each channel supports an output current of 700 mA with a fixed switching frequency of 250 kHz. The device features low static current consumption of 160 uA and includes shutdown functionality. Packaged in a 28-lead SSOP, it is designed for applications requiring efficient power management in space-constrained environments.

DC DC Switching Controllers Feature Summary

• Dual synchronous buck topology for independent channel control
• High efficiency operation via integrated synchronous rectification
• Low quiescent current capability for battery-powered systems
• Integrated shutdown pin for power management

DC DC Switching Controllers Applications

• Portable electronic devices requiring dual voltage rails
• Battery-operated instrumentation systems
• Industrial control modules with multiple logic levels
• Communication equipment power distribution networks

DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm tape-and-reel packaging configuration. Ensure compatibility with existing PCB footprints for the 28-SSOP package. Cross-reference electrical specifications with current datasheets to validate performance under intended operating conditions before finalizing procurement decisions.

DC DC Switching Controllers Selection Notes

Select this component when dual isolated or non-isolated buck converters are required from a single input source. Consider the 250 kHz switching frequency for balancing component size and efficiency. Evaluate thermal requirements based on the 700 mA per channel rating and the SSOP package thermal characteristics. Verify input voltage ranges align with system supply capabilities.

DC DC Switching Controllers Part Context

This part belongs to the LTC1142 series of dual synchronous buck controllers. It shares architectural similarities with other high-efficiency regulators but is distinct in its dual-channel configuration and specific pinout. The #TRPBF suffix indicates a lead-free, tape-and-reel variant suitable for automated surface-mount assembly processes.
