LT3570IFE#TRPBF

Overview

The LT3570IFE#TRPBF is a power management IC from Analog Devices Inc. featuring a buck converter, a boost converter, and an LDO controller. It integrates internal power switches with a 1.5A current limit for each converter. The device operates with an input voltage range of 2.5V to 36V. Key electrical parameters include a switching frequency of 2.1MHz to 2.75MHz and a quiescent current of 3.2mA. It provides adjustable output voltages and supports operation temperatures from -40°C to +125°C. The component is housed in a 20-TSSOP package.

Feature Summary

Integrates buck, boost, and LDO controllers within a single package
Includes internal power switches rated at 1.5A current limits
Supports wide input voltage ranges up to 36V
Features high-frequency switching for compact external component sizing

Applications

Portable battery-powered equipment requiring multiple voltage rails
Automotive infotainment systems
Industrial control modules
Communication infrastructure power supplies

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the 20-TSSOP footprint matches the design layout. Check for restricted supply conditions as availability may vary by region. Validate thermal performance requirements against the datasheet specifications.

Selection Notes

Select this component when a system requires simultaneous step-down, step-up, and low-dropout regulation from a single source. The integrated nature reduces board space compared to discrete solutions. Consider the 1.5A current capability for load requirements. Evaluate the 2.1MHz to 2.75MHz switching frequency for EMI constraints and inductor size trade-offs. Ensure input voltage stability remains within the 2.5V to 36V operational window.

Part Context

This part belongs to the LT3570 family of triple-output power management ICs. It combines three distinct regulator types to simplify power architecture. The IFE variant specifies the TSSOP-EP package type. Analog Devices designs these components for applications needing efficient multi-rail generation from varying input sources.
