Overview
The LT3692AEUH#TRPBF is a dual current mode PWM step-down DC/DC converter manufactured by Analog Devices Inc. It features two internal 3.8A switches and operates with an input voltage range of 7V to 36V. The device supports adjustable output voltages, including configurations for 1.8V, 2.5V, 3.3V, and 5V outputs. It utilizes a 32-WFQFN package with exposed pad for surface mount installation. The component is designed for applications requiring complex power supply tracking and sequencing.
Feature Summary
- Dual channel architecture with independent control pins for input voltage, shutdown, feedback, soft-start, UVLO current limit, and comparator functions per channel
- Supports external synchronization and multi-frequency operation for synchronized quad output configurations
- Simplifies complex power supply tracking and sequencing requirements through dedicated channel-specific control interfaces
Applications
- Quad output systems requiring 12V, 3.3V, 2.5V, and 1.2V rails with external synchronization
- Synchronized quad output designs utilizing 5V, 3.3V, 2.5V, and 1.8V levels
- Dual two-stage step-down converters generating 5V and 1.8V outputs
- Step-down converters with start-up current limiting capabilities for 12V to 3.3V and 2.5V conversion
Procurement Notes
Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the AEUH grade specifications against the official Analog Devices datasheet to ensure compatibility with required operating temperature ranges and electrical tolerances. Cross-reference the 32-WFQFN footprint dimensions during PCB layout finalization to guarantee mechanical fit.
Selection Notes
Select this component when designing systems that require precise output sequencing or tracking between multiple voltage rails. The independent control pins for each channel allow for customized startup profiles and fault management. Ensure the application benefits from the dual-channel topology to reduce component count compared to using separate single-channel regulators.
Part Context
This part belongs to the LT3692 family of dual synchronous buck converters. It shares architectural similarities with the LT3690 single-channel variant but offers dual independent channels. The device is categorized under PMIC - Power Management ICs and Switching Voltage Regulators within the Analog Devices portfolio.
Replacement Considerations
LT3692EUH#PBF is a related variant in the same family. Verify if the specific pinout and thermal characteristics are identical before substitution. Check if the TRPBF tape and reel packaging requirement can be met by alternative bulk tube packages if necessary.
