LT3570EFE#TRPBF

Overview

The LT3570EFE#TRPBF is a versatile power management IC from Analog Devices Inc. featuring an integrated 1.5A buck converter, a 1.5A boost converter, and an LDO controller. It operates with an input voltage range supporting both step-down and step-up configurations. The device utilizes a TSSOP-20 package with exposed pad for thermal performance. It supports switching frequencies up to 1.5MHz and functions within a junction temperature range of -40°C to +125°C.

Feature Summary

Integrates three distinct regulation stages: a synchronous buck converter, a boost converter, and an LDO controller within a single package.
Provides high current capability with 1.5A output capacity for both the buck and boost sections.
Supports flexible frequency adjustment to optimize efficiency and external component size.

Applications

Portable devices requiring multiple voltage rails from a single battery source
Systems needing simultaneous step-down and step-up conversion capabilities
Embedded applications utilizing combined switching and linear regulation

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the manufacturer is Analog Devices Inc. or its predecessor Linear Technology. Ensure the part number matches the exact electrical specifications required for your design, as variations exist within the LT3570 family.

Selection Notes

Select this component when a design requires a compact solution integrating buck, boost, and LDO functions. Consider the 1.5A current limit for load requirements. Evaluate the TSSOP-20 package constraints for PCB layout. Verify input voltage ranges align with the system's power source before finalizing the selection.

Part Context

This component belongs to the LT3570 series of mixed-signal power management ICs. It is designed to simplify power architectures by combining multiple regulator types. The device is manufactured by Analog Devices Inc., continuing the legacy of Linear Technology products in the portable electronics market.
