LT3692IUH#PBF

Overview

The LT3692IUH#PBF is a monolithic dual tracking switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3 V to 36 V and provides two adjustable output voltages from 800 mV to 34.2 V. The device delivers a maximum output current of 3.5 A per channel. It utilizes a fixed 2.5 MHz switching frequency and features a QFN-32 package. Quiescent currents are specified at 630 uA and 4 mA, with an operating temperature range spanning -40 C to +125 C.

Feature Summary

• Dual independent output channels with synchronized tracking capability
• Integrated high-efficiency synchronous buck topology
• Fixed internal oscillator for consistent noise performance

Applications

• Portable electronic devices requiring multiple regulated rails
• Industrial control systems with distributed power architectures
• Automotive infotainment and instrumentation modules

Procurement Notes

Verify the specific suffix #PBF confirms lead-free compliance and RoHS standards before procurement. Confirm the QFN-32 package dimensions match the target PCB footprint. Ensure the supplier source is authorized to guarantee component authenticity and traceability. Check datasheet revisions for any updates to electrical characteristics or thermal recommendations.

Selection Notes

Select this component when a compact solution for two closely related voltage rails is required. The fixed 2.5 MHz frequency allows for smaller external inductors compared to lower-frequency alternatives. Verify that the input voltage remains within the 3 V to 36 V operational window. Consider thermal dissipation requirements given the 3.5 A current capacity in the small QFN-32 package.

Part Context

This part belongs to the LT3692 series of dual tracking regulators designed for space-constrained applications. It integrates power switches and control logic into a single monolithic structure. The series targets designs needing efficient conversion from moderate input voltages to precise low-voltage outputs.

Replacement Considerations

LT3692EUH#PBF is a documented parameter-equivalent alternative within the same product family.
