LTC1142HVCG-ADJ#TRPBF

Overview

The LTC1142HVCG-ADJ#TRPBF is a dual synchronous buck switching regulator manufactured by Analog Devices Inc. It operates with a fixed switching frequency of 250 kHz and delivers up to 700 mA per channel. The device features an adjustable output voltage range, low quiescent current of 160 µA, and supports input voltages suitable for standard bus applications. Packaged in a 28-pin SSOP, it integrates power MOSFETs and PWM control circuitry for high-efficiency DC-DC conversion within the specified operating temperature range.

Feature Summary

• Integrates dual synchronous buck regulators with internal power MOSFETs
• Utilizes PWM control architecture for efficient step-down voltage conversion
• Supports adjustable output voltage configuration via external components

Applications

• Point-of-load regulation for digital circuits
• Battery-powered portable equipment power management
• Industrial control system voltage distribution

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm lot traceability and RoHS compliance documentation prior to integration. Ensure storage conditions meet manufacturer specifications to prevent moisture sensitivity issues. Validate package integrity against shipping damage indicators before assembly processing.

Selection Notes

Select this component when dual isolated or independent low-voltage rails are required from a single higher-voltage source. The 250 kHz frequency balances component size and efficiency. Verify that the 700 mA per-channel limit meets peak load demands. Consider thermal dissipation requirements for the SSOP package under maximum load conditions.

Part Context

This part belongs to the LTC1142 series of dual synchronous buck regulators. It shares architectural similarities with other LDO and switching regulator families from Analog Devices but is distinct in its integrated dual-channel topology. The HV variant indicates specific voltage handling capabilities compared to standard versions.

Replacement Considerations

Direct pin-compatible substitutes include the LTC1142HVCG-ADJ#PBF (tube packaging) or LTC1142HVCG-ADJ#TR (tray packaging). Cross-referencing with non-Analog Devices equivalents requires careful verification of pinout, thermal characteristics, and control loop stability.
