Overview
The LT3692AIFE#TRPBF is a dual current mode PWM step-down DC/DC converter featuring two internal 3.8A switches. It provides a single 3.3V output at 4A from dual inputs. The device supports an input voltage range of 3V to 36V. Key electrical parameters include a switching frequency of 2.5MHz and a maximum operating temperature of +125°C. It utilizes a TSSOP-EP-38 package for surface mount installation.
Feature Summary
- Dual independent channels with separate input, shutdown, feedback, soft-start, UVLO, current limit, and comparator pins
- Simplifies complex power supply tracking and sequencing requirements through dedicated control interfaces
- High-efficiency synchronous buck topology with integrated power switches
Applications
- Complex power supply tracking and sequencing systems
- Dual-input single-output step-down conversion applications
- Embedded systems requiring synchronized multi-rail power management
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the component matches the TSSOP-EP-38 package outline. Cross-reference the datasheet for the exact electrical specifications relevant to your design constraints before finalizing procurement.
Selection Notes
Select this component when dual independent channel control is required for a single regulated output. It is suitable for designs needing precise tracking between input sources or complex sequencing logic. The wide input voltage range accommodates various bus voltages. Verify thermal performance within the TSSOP-EP-38 package for your specific load conditions.
Part Context
This part belongs to the LT3692A family of dual tracking switching regulators. It is designed for applications requiring independent control of multiple power rails while maintaining a unified output regulation. The series offers flexibility in managing power-up and power-down sequences through dedicated pin configurations.
Replacement Considerations
LT3692AEFE#PBF is a tube-packaged variant of the same functional device. Verify that the packaging difference does not impact your assembly process. Both parts share identical electrical characteristics and pinouts.
