LTC1142HVCG#TRPBF

Overview

The LTC1142HVCG#TRPBF is a dual high-efficiency synchronous buck switching regulator controller manufactured by Analog Devices Inc. It integrates power MOSFETs and PWM control circuitry to step down input voltage to stable adjustable outputs. The device operates at a fixed switching frequency of 250 kHz and supports an output current of 700 mA per channel. It features a low static current of 160 µA and functions within an ambient temperature range of 0°C to +70°C. The component is housed in a 28-lead SSOP package and utilizes a buck topology for efficient DC-DC conversion.

Feature Summary

• Integrates dual synchronous buck regulators with internal power MOSFETs
• Provides adjustable output voltage capability via external feedback
• Optimized for high efficiency through synchronous rectification

Applications

• Battery-powered portable electronics requiring dual voltage rails
• Industrial control systems needing efficient step-down regulation
• Communication equipment power distribution networks

Procurement Notes

Verify the exact suffix #TRPBF against official Analog Devices documentation to confirm tape-and-reel packaging and lead-free compliance. Confirm availability status as supply may be limited or subject to factory special orders. Ensure the SSOP-28 package matches your PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when dual independent adjustable outputs are required from a single controller IC. The 250 kHz switching frequency offers a balance between component size and efficiency. Verify that the 700 mA output current per channel meets the load requirements of the target application circuits.

Part Context

This part belongs to the LTC1142 series of dual synchronous buck controllers. It shares the SSOP-28 package form factor with other variants in the family but differs in output configuration and specific electrical characteristics. The #TRPBF designation indicates a specific reel packaging option compliant with RoHS standards.

Replacement Considerations

Check for direct pin-compatible alternatives within the LTC1142 family, such as the LTC1142HVCG#PBF for tube packaging. Evaluate other dual buck controllers from Analog Devices if specific current or frequency parameters require adjustment.
